Question 0

VSEPR

Answer 0

Valence shell electron pair repulsion

To minimize repulsion e- move away from each other

Question 1

Electronegativity

Answer 1

Atom’s ability to attract e- to itself

Question 2

EN Values

Answer 2

.5-2 = polar covalent

Less than or = .4 covalent

> = 2 ionic

Question 3

What does polarity effect?

Answer 3

Properties

Solubility

BP MP

Reactivity

Question 4

Atomic orbital

Answer 4

e- treated as waves

Quantum mechanics

Mathematical description of wave Y

Question 5

Y^2

Answer 5

Region of space around nucleus

Probability of finding an e- is high

Question 6

Wave function

Answer 6

Allows us to assign a numeric value for each location in 3-D space relative to nucleus

Orbital

Spin in opp. directions

Question 8

Aufbau

Answer 8

Start at lowest “n” first

Question 9

Hund’s rule

Answer 9

Don’t pair e- until every orbital has 1e-
