Question

Binary ionic compound zinc and chlorine?

Answer 1

valency of Zn is +2 and valency of cl is -1
therefore
Zn^++ Cl^-
2 1
ZnCl2
as zinc chloride made from ionic bond of Zn ion and chloride ion.

Answer 2

Answer:

ZnCl2

Explanation:

Zinc has a charge of 2+

Chlorine has a charge of 1-

So far, our formula looks like this:

Zn^2+Cl^1-

Reversing these two charges and using absolute value, our formula would then look like this:

Zn1Cl2

So our formula is ZnCl2.
