Quantum Numbers - Screodinger's Wave Equation

Question 1

Principle Quantum Number Letter & def.

Answer 1

(n) a positive integer describing the energy level (orbital) of the electron

Question 2

Angular Momentum Quantum Number letter & def.

Answer 2

(l) can be any integer from 0 to n-1, and describes the shape of the orbital (ex. s, p, d)

Question 3

Magnetic Quantum Number letter & def

Answer 3

(m) can be any integer from -l to +l and describes the orientation of the orbital (ex. px, py, pz)

Question 4

spin quantum number letter & def

Answer 4

there is no letter - it only has two values (+1/2. -1/2) which indicate the two fundamental spin states of an electron in an orbital
