Chemically Zinc group elements closely resemble $........$

A
$\text{I A}$ group
✓
$\text{II A}$ group
C
$\text{III A}$ group
D
$\text{IV A}$ group

✓

Answer

Correct option: B.

$\text{II A}$ group

Zinc belongs to $\text{IIB}$ and it closely resembles $\text{IIA}$ because of the completely filled valence orbitals. The reason is in $\text{IIA}$ group all the elements have completely filled $s-$orbital while in $\text{IIB}$ group the elements have completely filled $s$ orbital along with $d-$orbital.
