Unit 5 Test

Question 1

Hund’s rule

Answer 1

Electrons will pair up only when all orbitals in the same sublevel have one electron
When single electrons occupy different orbitals of the same sublevel, they all have the same spin

Question 2

Infrared light

Answer 2

A type of electromagnetic radiation

Question 3

Pauli exclusion principle

Answer 3

The restriction on the placement of electrons in the same orbital
If two electrons occupy the same orbital, they must have opposite spins (clockwise vs. counter-clockwise)

Question 4

Afbau principle

Answer 4

Electrons will only occupy a p-orbital only after the previous s-orbital is completely full
Electrons can only begin to occupy energy levels with the next highest integer destination only after all orbitals on the energy level below it are occupies

Question 5

Orbit definition

Answer 5

Fixed pathways

Question 6
