How do you know how many electrons there are in each energy level?

So in level 1: 2 electrons level 2: 8 level 3: 18 level 4: 32 ? an element with an atomic number of 59 how many electrons would it have in each energy level?

Answer #1

Ok been a long time since HS chemistry but the atomic number is the number of electrons or protons in the atom. So 2 + 8+18 is 28. 59 -28 = 31. So 4th shell should have 31 I think?
