How many electrons can be in each energy level?

Answer 1

1st level : 2

2nd level : 8

3rd level : 18

4th level : 32

You can figure it out by the formula 2n^2 (2 times n squared) where n is the energy level.

So, level 5 is 2 (5x5) = 50.

The above is the maximum number, not necessarily the number in each energy level in any given element, because an element does not necessarily fill an entire energy level before moving on to the next one.

Answer 2

the 1st level consists of 2 electrons. After that it is 8.

*At least until you get into D and F configurations in which case you fill in electrons as follows:

1s2 -> 2s2 -> 2p6 -> 3s2 -> 3p6 -> 4s2 -> 3d10 -> 4p6 -> 5s2 -> 4d10 -> 5p6 -> 6s2 -> 5f14 -> 5d10 -> 6p6 -> 7s2 -> 6f14 -> 6d10 -> 7p6

Where 1s2: 1 is the energy level, s is the orbital, 2 is the max number of electrons it can hold.

So an energy level can contain from 2 - 32 electrons in one energy level.

Answer 3

The number of electrons that can occupy each energy level is given by 2n^2, where n is the principal quantum number of the energy level. For example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.

Answer 4

in the first energy level there cold be 2 and in the second level there could be 8 but the others cant go passed 8

Answer 5

In the first level, there can only be two. In the second level, there can be up to eight. And, in all of the leves following, there can be no more than eight.

Answer 6

Doesn't that depend on the element? I think there can be from 0 to 8.

Answer 7

2, 8, 18, 32
