General electronic configuration ns2np2 is of carbon family.

General electronic configuration ns2np1 is of boron family.

General electronic configuration ns2np5 is of halogen family

Answer 2

General electronic configuration is as follows -

• Group IV A or group 14 elements are called Carbon family. Their electronic configuration is ns²np².

• Group V A or group 15 elements are called Nitrogen group or pnictogens. Their electronic configuration is ns²np³.

• Group VII A or group 17 elements are called halogens. Their electronic configuration is ns²np⁵.

• Group II A elements are called Alkaline Earth Metals. Their electronic configuration is [Noble gas] ns².
