Quantum Numbers
Chemistry II
Principal (n)
• Energy level
– 1, 2, 3, etc.
Momentum / Shape (ℓ)
• Orbitals making a subshell
– All numbers between 0 and n-1
– 0=s
1=p
2=d
3=f
Magnetic (mℓ)
• Number of orbitals
– mℓ = all numbers -ℓ through +ℓ
Magnetic (mℓ)
• Orbital shape
– s: sphere
– p: figure-8
– d: clover
Electron Spin (ms)
• Up or down (+ ½ or – ½)
Orbitals and Electrons
• Each orbital holds 2 e-
– s subshell = ___ orbitals = ___ e– n=2 = ____ subshells = ___ orbitals = ___ = electrons
`
WRAP UP
1.List all of the orbitals present
in the 4th shell.
WARM UP
1.List the 4 quantum numbers,
using at least 2 terms or
symbols for each.
WRAP UP
• Give the set of quantum numbers that
would correspond to the following:
– An up electron in the 3rd f orbital in the 5th shell
– A down electron I the 1st p orbital of the 3rd shell
