Answer 1

electrons occupy the lowest energy level that can recieve it

Question 2

Pauli Exclusion Principle

Answer 2

no two electrons in the same atom can have the same set of 4 quantum numbers (electrons will have to have different spin q.n.)

Question 3

Hunds Rule

Answer 3

orbitals of equal energy are each occupied by one orbital is filled by a second and all singly occupied orbitals must have the same spin

Answer 4

has the element, up/down arrows
(the visual one)

Question 5

Answer 5

number of electrons are shown by using superscripts

Question 6
