the valence of CaCl2 is 2 because its not necessary that CaCl2 is always attached in hydrated form...... the basic thing which u study in your school classes that the outermost shell of both the element must be completed. so cacl2 has the valency of 2 because ca is electropositive. think it

∙ 10y agoCa is in group 2 so it has a total of 2 valence electrons.
Cl is in group 7 so it has a total of 7 valence electrons.
However, since Cl is 2, therefore 2X7=14 valence electrons for Cl.
Thus, 14+2(valence electrons for Ca)=16 total electrons.
