How many electrons can be on each energy level?

Answer 1

The rule for determining the number of electrons is 2(n2) The number of energy levels in represented in N. For example, on the third energy level, you would square 3 to get 9, and then multiply 9 by 2 to get 18. The third energy level can hold up to 18 electrons.

shell 7- 98
shell 8-128
shell 9-162
shell 10-200
3 but if other element are in can be 4 but most likely 3

ONLY TWO and they have to have opposite spins. This is Known as the Paulie exclusion Principle. Discovered by Linus Paulie and was the reason for one of his Nobel Prizes.

Answer 2

The number of electrons that can occupy an energy level is given by the formula 2n^2, where n is the principal quantum number of that 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 3

K:2 Electrons

L:8 Electrons

M:18

Answer 4

The number of electrons in any shell can be found using the expression 2n2, where 'n' is the number of energy level (electronic shell of an atom).
