Answer:

3. Equal numbers of  protons and neutrons

Nucleus 3 is therefore the most stable.

What's the charge on Ni in the compound NiCi3? *
ss7ja [257]

Answer:

+3

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.

Hope it helped! Rate my answer a 5 star if correct.
