We are asked to determine the value of ℓ when m= 4.

Possible values of the quantum numbers:

principal quantum number →energy level in orbitals and its value could be any positive integer starting from 1 to infinity

angular momentum quantum number (ℓ)→ (l) has to be at least 1 less than n, range of values from 0 up to (n-1)

▪ Each ℓ value corresponds to a subshell:

 = 0→ s subshell
 = 1→ p subshell
 = 2→ d subshell
 = 3→ f subshell

= 4→ g subshell

• magnetic quantum number (m)→ range of values from - to +

▪ The m values (for each ℓ) represent electron orbitals for the subshell:

s subshell→ 1 orbital
p subshell→ 3 orbitals
d subshell→ 5 orbitals
f subshell→ 7 orbitals

g subshell→ 9 orbitals

spin quantum number (ms) → can only have two possible values +½ (spin up electron) or½ (spin down electrons)

• Note that 1 orbital can hold a maximum of 2 electrons→ 1 spin up (+½) and 1 spin down (–½)
