Answer:

Atomic Number:-

Beryllium=4

Phosphorus=15

ELECTRONIC CONFIGURATION:-

of :-

Beryllium:- 2,2

Phosphorus:- 2,8,5

GROUP:-

Beryllium:- group 2

Phosphorus:- group 15

Valency :-

Beryllium:-2

It will lose electron from its last shell for completing octane and follow stable noble gas configuration and get positive charge (Be+) .

Phosphorus:-3

It will gain electron for completing octane and follow stable noble gas configuration and get negative charge (P-)

Thank you!
