Answer:
*⃣_____________________________❤
Atomic Number :=
a = 9
electronic configuration : k = 2
==================== l = 7
b = 8
electronic configuration : k =2
====================l = 6
c = 12
electronic configuration : k =2
==================== l = 8
====================m = 2
d = 16
electronic configuration : k = 2
====================l = 8
====================m = 6
So A is having 7 electrons in outermost shell
No element is having 0 valency
c is metal because two electrons are present in the outermost shell it will lose these two electrons to form cation
outermost electrons
C = 2
d = 6
c3d
the bond will be ionic bond c is metal whereas d is non metals of ionic bond will be formed by the transfer of electrons from C to D
Atomic size inversely proportional to Atomic number
= 9 atomic less so size is highest
