Please help me with this question's solution
Dear Student
Mass number of element A = 28
No of neutrons = 14
So its atomic number = Mass number - No of neutrons = 28-14 = 14
Electronic configuration of A = 2,8,4
Valency is 4.
Second question is based on same concept. Try yourself. If any query arise ask your doubt. We will answer it.
Regards
