Solution:

The electronic configuration of given element is as
$1{{s}^{2}},2{{s}^{2}},2{{p}^{6}},3{{s}^{2}},3{{p}^{6}},3{{d}^{10}},4{{s}^{2}},4{{p}^{3}} $
This is the element of fifth group because there are five electron in outermost shell. Hence, the property of this element is similar to nitrogen family.
