Question 19

The De Broglie Cont. tells us that…

Answer 19

the more massive the object, the smaller its associated wavelength

Question 20

Principle Quantum number (n)

Answer 20

represents size (ex: 1s, 3p, 5d)

Question 21

Angular Momentum Quantum number (l)

Answer 21

represents shape, can be 0,1,2, or 3
s=0
p=1
d-2
f=3

Question 22

Magnetic Quantum number (m)

Answer 22

determines the number of orbitals in a subshell
(can have values of -l to 0) (ex: since p=1, there are 3 orbitals; -1, 0, and 1)

Question 23

Spin Quantum number

Answer 23

indicates orientation; electrons can be spin up or spin down

Question 24

Hund’s rule

Answer 24

every orbital in a subshell is singly occupied before any orbital can be doubly occupied. Electrons in singly occupied orbitals have the same spin

Question 25

Aufbau Principle

Answer 25

“Building up” principle, meaning that electrons fill lower energy orbitals before higher ones

Question 26

Pauli Exclusion Principle

Answer 26

Two particles with 1/2 integer spin cannot occupy the same quantum state

Question 27

Heisenberg Uncertainty Principle

Answer 27

Cannot know the location and velocity of an electron simultaneously
