Based on the Lewis/electron dot representation

of the two atoms, predict the ratio of metal

cationic (+) atom to nonmetal anionic (-) atom in

the compound.

.Ca:

A. 1:1

B. 1:2

C. 2:1

D. 3:1

Respuesta :

I’m pretty sure The answer is B

1:2 is the correct ratio between cationic atom and nonmetal anionic atom.

Calcium atom belongs to second group elements in the periodic table means it has two electrons in its outermost shell so it combines with two atoms of seven group because group seven elements needs one electron for completing outermost shell and attain stability.

So two atoms of group 7 elements make ionic bond with one calcium atom i.e. the ratio is 1: 2 so we can conclude that the cationic atom bonded with nonmetal anionic atom at the ratio of 1: 2.
