The number of orbitals associated with quantum numbers n = 5, m_s = +1/2
is:
Option: 1 25
Option: 2 11
Option: 3 15
Option: 4 50
 

Answers (1)

We have:

n = 5, ms = +1/2

Thus, the values of l are from 0 to (n-1)

l = 0 to 4

Thus, values of l are 5s, 5p, 5d, 5f, and 5g

Now, the total number of orbitals = n^2 = 5^2 = 25

Therefore, Option(1) is correct.
