Answer 1

Hey there again! There's no easy way to show how to do this on a computer so I've attached a couple of websites and powerpoints that are helpful for solving this type of question. I'd say review Hund's Rule and Pauli's Principle.

1)Hund's rule: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.

2)Pauli's Exclusion Principle: No two electrons in an atom can have identical quantum numbers

Here's the link to the powerpoint: http://staffweb.psdschools.org/rjensen/powerpoints/e_filling_order.pdf

Answer 3

What doesn't make sense? Can you point to a particular definition or something so that it can become easier to explain the concept to you?
