An ion has a charge of 3+.if this ion has 8 protons, how moany electrons does it have? a 3 b 5 c 7 d 8 e 11

The answer is B

Explanation:

3+ means there is 3 more protons than electrons.

So electron need 3 more (-ve) charge in order to have the same charge as proton to become neutral atom (no charge).

e + 3 = 8

e = 8 - 3

= 5

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
