Question

bond formation of cacl2

Answer 1

Hi !

Electronic configuration of Calcium = 2,8,8.2

To attain stability it needs to lose two electrons .

Ca + 2e- -----> Ca ²⁺




Chlorine's electronic configuration = 2,8,7

It needs to gain 1 electron to attain stability

As Calcium needs to give away its two electrons , and 1 atom of chlorine needs only 1 electron more , calcium forms covalent bond with 2 atoms of Chlorine as both would require 1 electron each .
