Question

The electonic configuration of four different elements is given below. Identify the group $14$ element among these.

• A. $\left[He\right]2s^1$
• B. $\left[Ne\right]3s^2$
• C. $\left[Ne\right]3s^{2}3p^2$
• D. $\left[Ne\right]3s^{2}3p^5$

Answer 1

The correct option is C $\left[Ne\right]3s^{2}3p^2$

The general elctronic configuration of group $14$ elements is [noble gas] $n{s}^{2}n{p}^2$.
$\left[Ne\right]3s^{2}3p^2$ is electronic configuration of Silicon which belongs to group $14$.
Hence correct option is c.
