FREE Expert Solution

We are being asked to determine which of the given statements are TRUE for a 3s orbital.


To solve this problem, let’s first define and determine the possible values of the four quantum numbers:

principal quantum number (n)  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:
