# Problem: What are the possible sublevels for n=2?A) sB) s,p C) s,dD) s, p, d

###### FREE Expert Solution

We are being asked to determine the possible sublevels for n = 2

Let’s first define the quantum numbers.

• the principal quantum number (n) → energy level in orbitals and its value could be any positive integer starting from 1

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/sublevel:
