$\huge\fcolorbox{black}{pink}{Answer-}$

Mg = 2,8,2

O = 2,6

Si = 2,8,4

Cl = 2,8,7

N = 2,5

Answer 2

Answer: mg-1s^2 2s^2 2p^6 3s^2,N-1s^2 2s^2 2p^3

O-1s^2 2s^2 2p^4,Si-1s^2 2s^2 2p^6 3s^2 3p^2,Cl-1s^2 2s^2 2p^6 3s^2 3p^5

Explanation:you have to first draw the Aufbau diagram to can find the electronic configuration.
