Question

What's the charge on Ni in the compound NiCi3? *

+1
+2.
+3
- 7
-2.
3
you can't tell

Answer 1

+3

Step-by-step explanation:

Chlorine is anion with a -1 charge. But they are three chlorine atoms.

-1 * 3 = -3

So they have a -3 charge.

So to balance the compound, the nickel has to be a cation with a +3 charge.

-3 + 3 = 0

Furthermore, a chemical bond always has a 0 charge. Remember that.
