Correct option - C) K
In picture - O.A.M. - Orbital Angular Momentum
- l(s) =0, l(p)= 1, l(d)= 2 ,l(f)= 3.

Brother it ends with 2p6
no how
3s2
it's atomic number is 12
It is Mg2+ not Mg
what is the difference could u plz tell
k I understood
Mg2+ is a stable ion while Mg is an atom
I understood

Mg:1s2 2s2 2p6
Fe:1s2 2s2 2p6 3s2 3p6 4s2 3d6
k:1s2 2s2 2p6 3s2 3p6 4s1
cs: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6
so, that's y for l (s)=0 p=1 d=2
so, k is the correct answer
option (c) is correct
I hope it will help for u ☺.
