Q. Given is the electronic configuration of element $X$
$(K)-(2), (L)-(8),(M)-(11) (N)-(2)$
The number of electrons present with $l= 2$ in an atom of element $X$ is

Structure of Atom

Solution:

$X_{23}: 1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 3d^{3} 4s^{2}$.
No. of electron with $l= 2$ are $3 (3d^{3})$
