Electrovalent- It is a form of bonding whereby one or more electrons are transferred from one atom (metallic) to another atom (non-metallic) so as to attain either duplet or octet stable state. It is also called ionic bonding. It is found in Nacl Kcl, CaCL , CaO etc.

Example of  Electrovalent Bonding

 

BEFORE COMBINATION
Na Cl
Na Cl
p = 11 p = 17
e = 11 e = 17

AFTER COMBINATION
after combo ac
Na Cl
p = 11 p = 17
e = 10 e = 18
