Question

find the velency of cacl2 by Criss cross method ​

Answer 1

Explanation:

2 os the valency of cacl2

Answer 2

Answer:

Calcium - 2         Chlorine - 1

Explanation:

We criss cross the valencies of the elements to get the compound name and thus if we criss cross it again, we can get the valency of the elements each.

In the Compound CaCl2,

Ca- 1    and    Cl - 2

Now criss cross and we get,

Ca - 2     and  Cl - 1

Therefore, Calcium has a valency of 2 electrons while Chlorine has a valency of 1 electron.
