You can tell the number of electrons by counting across from left to right. It is also the number of electrons each track (or orbital) can hold. It goes 2, 8, 8, 18, 18, 32. Also, it is organized by weight, or the atomic mass (AMUs) from top to bottom and left to right.

Each row in the periodic table represents an orbital. The first orbital can only hold two electrons. The next two hold eight. The fourth and fifth rows hold eighteen. The last two rows holds thirty two electrons. The number on top of each of the abbreviations is called the atomic number. This tells you how many electrons there are in that element.

You can tell the number of electrons be counting across from left to right. like theres two squares across from each other and you just count them and thats how many electrons. when you go the second round its 8,8,18,18, and then 32.
sofi francis // February 28, 2008 at 1:35 pm
while I think that the element goes left and right. I don’t know the why the location of electron is there.

The periodic table shows you how many elctrons are in each orbit by the number of elements in each row. It also tells you how many electrons in the atom by the atomic number. The number of protons is also the same as the number of electrons. Also the elements show the weight of the electron as the number after the decimal point in the atomic mass.
Myoung Kim // February 28, 2008 at 1:37 pm
You can see that as you go to the right side of the table, the atomic mass gets bigger and so as the atomic number. You can also see that as you go down the table, the element can hold more electron(s) and orbirtal(s)

As you from left to right on the Periodic Table of Elements and you count every square it tells you how many electrons to put on each track. The squares also tell how many electrons there are(atomic number). The first track for electrons can only fit two electrons then 8,8,32 and so on.
Liam McNeill // February 28, 2008 at 1:39 pm
The Periodic Table gives you the possible amount of electrons in each orbital. The atomic number also gives you the amount of electrons in an atom. It does this because the atomic number is the number of protons which is equal to the amount of electrons.
Bounahra Kim // February 28, 2008 at 1:39 pm
The clues that the periodic table gives you that the way the rows are lined up from left to right. As you can see the first row has only two elements which means that they only have two electrons. The second row has 8 elements, which mean that all the elements in that row have 8 electrons. It continues to 18 elements in the fourth row and 32 elements in the sixth row.
Ricardo A // February 28, 2008 at 1:40 pm
It show the electrons it have and it show the each track (or orbital) can hold. It goes to 38 ,39, 50 and 80, also it is organized by the weight.
Noah L // February 28, 2008 at 2:28 pm
The row that an element is on tells how many orbitals are occupied by electrons (maximum copacity per row: first row=2 electrons, second row =8 electrons, third row=8 electrons, fourth row= 18 electrons, fifth row=18 electrons, sixth row=32 electrons, seventh row= 32 electrons) The atomic number tells you how many electrons are actually in the element.
coleman // February 28, 2008 at 2:29 pm
the periodic shows how many electrons are in each orbital by the number on each row, and the noble gases are on the far right and its also organized by weight and color.
Devon M. // February 28, 2008 at 2:30 pm
The organization of the periodic table tells you how many electrons the element has and how many electrons can fit on one orbital.
Hugh C. // February 28, 2008 at 2:33 pm
The periodic table is organized so that the elements with the fewest protons and electrons are near the top. The first row has two, which means that there can be at most 2 electrons. The second row has 8 elements so that means that you can have up to 10 elements, 2 plus 8. The third row has 8 too, and the fourth and fifth rows have 18, and the rest have 32.
BRANDON M // February 28, 2008 at 2:34 pm
The clues that the periodic tabled gives to people is that the atomic number is number of electron and proton and if you take away the atmoic mass you get the number of nuertrons.
Arsen Tufankjian // February 28, 2008 at 2:35 pm
The weight of the element increases as you go from left to right. As the weight goes up so does the number of sub atomic particles. Also, each horizontal line of elements, when stacked on top of each other (like in the periodic table) the number of orbitals goes from 2, 8,8, 18,18, 32, 32, 64, 64, 128, 128…
Jacob B // February 28, 2008 at 2:35 pm
The periodic table tells you how many electrons can be on each orbitals. Every time you go down one row thats how many orbitals are in that atom and depending on how many atoms are in that row is how many electrons can be on that orbital. For example mecurey has six orbitals because its in the sixth row.
Alexis W. // February 28, 2008 at 2:37 pm
As you go across from left to right the atomic mass and the atomic weight increases. As you go down the columns the numberr of electron(s) or orbital(s) increases. It goes 2, 8,8,18,18,32
Isaac A. // February 28, 2008 at 2:38 pm
The periodic table gives a clue how many amount elctrons in each obitral. you go right to left to see how many. Like if there 8 elements in a row that means there can be 8 electrons in a obitral. The amtioc number tells how many protons in the element and that means there is the same amount of electrons they are.
Nolan BaTeman // February 28, 2008 at 2:44 pm
The periodic table is shown so the number of elements in each row is equal to the number of electrons in each orbital. The first row has two elements, so the first orbital on an element has two electrons. same with the second row. And the row after that. but the forth row, that is equal to the fourth orbital, has 18 electrons on it.
Connor J. // February 28, 2008 at 4:09 pm
The Periodic Table of the Elements is organized so that each row from the top shows how many electrons can be on the orbital. Such as 2 on the first orbital, 8 on the next, 8 on the next, 18 next, etc.

Casey.D // February 28, 2008 at 4:14 pm
You can tell the number of electrons by counting from left to right. In the first row there are too in the second there are 8,8,18,18,32
Natalie A // February 28, 2008 at 4:14 pm
The periodic tabe is arranged so that each row repersents an orbital. The first row has 2 the seconded row has 8 the third row also has 8 etc. they are also arranged by weight if you look at the very bottom on the right you can see that it has the biggest atomic mass in amu’s.
Morgan // February 28, 2008 at 4:15 pm
The number of elements on each row of the periodic table tells you how many electrons can fit on one orbital. The number of electrons each orbital can hold in order are 2, 8, 8, 18, 18, 32.
Dexter M. // February 28, 2008 at 4:15 pm
Each line down adds a nother orbital the orbitals follow this pattern 2,8,8,16,16,32,32 goeing sideways you are adding another elcectron
Jesse D. // February 28, 2008 at 4:16 pm
The atomic number (the number on top of the atom) shows how many electrons are in the atom. Also, the periodic table is arranged so that the top row shows the maximum number of electrons in each orbital. The top row only has 2 elements so the first orbital can only have two electrons
Stephen W. // February 28, 2008 at 4:17 pm
The periodic table is organized in rows from least to biggest amounts of the atomic number and the atomic mass.The periodic table also shows that the first row has two elements then the next two rows has 8 elements then the next two has eighteen then thirty-two elements, which shows which orbit the electrons are in.
sabrina L // February 28, 2008 at 4:17 pm
the pericodic table of e.ements is organized to show how many electrons can be around in the nucles. such as eight on the frist row and 8 for ever nest row
Keshia // February 28, 2008 at 4:18 pm
The Periodic table of elements is organized on how many electrons can be on its orbital. For example from left to right, on the top row its 2,and on the 3rd row its 8, and etc.
Tim P. // February 28, 2008 at 4:18 pm
When you see the first row there is only two elements and each element has two electron. In the second row there are eight elements and each one has 8 electrons. Which means the number of elements in each row is the number of electrons they have. As you go down and see the rows the number of element is the same number of electrons the elements have in the row.
Hannah C. // February 28, 2008 at 4:18 pm
The rows in the Periodic Table have the same amount of elements in a row as the amount of electrons in an orbital. The first row has 2, the next two have 8, and 18 in the next two, and so on.
Isaac J. // February 28, 2008 at 4:19 pm
The Periodic Table is organized in a way where the number of elements in each row represents the number of electrons and each row represents an orbital. 2 electrons can fit on the first row, 8 on the second and third rows, and 18 electrons on the fourth and fifth rows. 32 electrons can be on the sixth row and 23 can fit on the last orbital.
M5 // February 28, 2008 at 4:20 pm
The periodic table tells you the number of electrons each orbital can hold. It goes like this 2, 8, 8, 18, 18, 32, and 32. Also the periodic table is organized by weight, and AMUs from top to bottom and left to right.
Zahri D // February 28, 2008 at 4:20 pm
The periodic table tells you how many electrons can be on each orbital by how many elements are in each row across. For instance, the first row at the top has two elements on it so the first orbital in every atom can have up to two electrons on it. The next row down has eight elements on it so the second orbital of every atom can have up to eight on it. This continues all the way down the Periodic Table.
Sean B. // February 28, 2008 at 4:21 pm
The Periodic Table shows you how many electrons their are on each ring of an atom by how many elements their are in each row. The atomic number also shows you how many electrons their are in a specific atom. Finding the number of protons is the same way to finding electrons. Electrons weight about nothing. The weight of the element rises as you go left to right.
Lily A. // February 28, 2008 at 5:22 pm
It is organized from left to right in order of the numbers.
Katelyn.H // February 28, 2008 at 5:25 pm
The periodic table is set up to tell you how many electrons are on each ring. If you go along the very first period there are two elements so there are two electrons on the first ring. If you look along the second period there are 8 elements so there are 8 electrons on the second ring. This continues for every period.
Lily A. // February 28, 2008 at 5:25 pm
The electron is on top because it orbits around so it makes sence for it to be there
Grania P. // February 28, 2008 at 5:27 pm
It is organized from left to right by the number of electrons in the atom. Also, by how many atoms per orbital. The first orbital can hold two electrons, the second and third can hold 8, and then the next two can each hold 18, and the last can hold thirty-two.
John T. // February 28, 2008 at 5:27 pm
It is organized left to right because going to left to right the atomic mass increases and the atomic number increases as well. So it shows the number of electrons an orbitals.
Iqbal H. // February 28, 2008 at 5:28 pm
the periodic table is oder by electron orbital can hold well it goes like 2, 8, 8, 18, 18, 32, and 32. it’s also oder by the weight and oder by the gas witch pretty much same jobs
Grace // February 28, 2008 at 5:28 pm
The perodic table shows you how many electrons fit on every orbital by how many elements there are in every period. The atomic number shows you how many electrons are in the element. By knowing the number of electrons, you will be able to figure out which orbital an electron goes in by looking at how the elements are arranged on the periodic table.
Courtney // February 28, 2008 at 5:30 pm
You can tell how many electrons there are on the orbitals by looking at the rows and how many numbers there are at the top.
Alexis Flolwers // February 28, 2008 at 5:32 pm
The periodic table shows how many electrons go on each track(or an Orbital) are going to be in the atom.
mahad // February 28, 2008 at 5:32 pm
It goes 2, 8, 8, 18, 18, 32 because the guy how design did it that way. It’s also not that confusing and the numbers of electrons = numbers of protons.
Garang A. // February 28, 2008 at 5:33 pm
It’s organized by the number of electrons in an orbital.The number of electrons is always the same with the number of protons. For example the first track contains two electrons as the maximum.
jacob M. // February 28, 2008 at 5:35 pm
The Periodic Table shows how many electrons are in an orbit on the element. To find the amount you look at the top number. The top number also shows how many protons are in the nucleus of the element.
Abdi Ali // February 28, 2008 at 5:35 pm
You can tell where the number and locations of electrons by the number of protons in the atomic number. For example the number of electrons is 6 and the protons is 6 and the nuetron is 6.
Abdifitah // February 28, 2008 at 6:09 pm
The periodic table shows how many electrons are orbital around and that the first track can hold two, second row 8, third row 8, fourth row 18, fifth 18 again, and so on
