Quantum Mechanical Model

Question 1

Heisenberg’s Uncertainty Principle

Answer 1

It is impossible to identify the speed & location of an E- at the same time; it is inaccurate to say E- are in set orbitals.

Question 2

Atomic Orbitals & Key Characteristics

Answer 2

Three dimensional area of probability where an E- is most likely located (90%)
1. Certain Orientations (Direction)
2. Have certain sizes (small > big); Principle E Level
3. Certain shapes (Sphere, Dumbbell, Butterfly, Crazy): S, P, D, F
4. Each orbital can hold a max of 2 E-

Question 3

Four Quantum Numbers & Values

Answer 3

N: Principle Energy Level (N: 1-7)
ℓ: Angular Momentum, Sublevel or Shape, ℓ: S0, P1, D2, F3
Mℓ: Magnetic QN, Specific Orientation, (Number Line)
Ms: Magnetic Spin,↑+½ ↓-½
