The number of unpaired electron-s- in Mg-2- ion is-zerothreetwoone

Question

Toppr Admin · Accepted Answer

The electronic configurations are given below-12Mg-KLM28212Mg2-KL28-noble gas configuration- no unpaired e-x2212-Hence- there are zero unpaired electrons in Mg2-

The number of unpaired electron(s) in $M g^{2 +}$ ion is:
zero
three
two
one

The electronic configurations are given below:
$_{12} M g : \begin{matrix} K & L & M 2 & 8 & 2 \end{matrix}$
$_{12} M g^{2 +} : \begin{matrix} K & L 2 & 8 \end{matrix}$
(noble gas configuration, no unpaired $e^{-}$ )
Hence, there are zero unpaired electrons in $M g^{2 +}$ .

The number of unpaired electron(s) in Mg2+ ion is:zerothreetwoone

The electronic configurations are given below:12Mg:KLM28212Mg2+:KL28(noble gas configuration, no unpaired e−)Hence, there are zero unpaired electrons in Mg2+.
