Refer to the Periodic table and identify an element among following similar to sulphur.

• A. $O$
• B. $N$
• C. $P$
• D. $As$

Answer 1

The correct option is A $O$

$N,P$ and $As$ belongs to group $15\left(VA\right)$ of the periodic table. They have the electronic configuration $n{s}^{2}n{p}^3$.
Whereas $O$ and $S$ belong to the group $16\left(VIA\right)$ of the periodic table.
They have electronic configuration $n{s}^{2}n{p}^4$.
Thus, $O$ and $S$ are similar.
