In this problem, we are being asked to determine the maximum number of electrons in an atom that has a quantum number of n = 4, ℓ = l, and ml = 0.
Next, let’s define and determine the possible values of the quantum numbers:
• the 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:
ℓ = 0 → s subshell
ℓ = 1 → p subshell
ℓ = 2 → d subshell
ℓ = 3 → f subshell
• magnetic quantum number (mℓ) → range of values from -ℓ to + ℓ
▪ The mℓ 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
What is the maximum number of electrons in an atom that can have the following quantum numbers?
n = 4, l = 1, ml = 0
