Chemistry Question on Structure of atom

What is the total number of electrons that can have the values n=2,l=1,s=1/2n=2, l=1, s=1 / 2 in the electronic configuration 1s22s22p3?1 s^{2} 2 s^{2} 2 p^{3} ?

A

1

B

3

C

5

D

7

Answer

3

Explanation

Solution

n=2,l=1,s=1/2n = 2, l= 1, s= 1/2,
Orbital = 2p32p^3
No of electrons =3= 3
