PLEASE HELP SMART PPL!!! How many protons does an ion with 10 electrons and a charge of +2 contain?

10,8,13,12,11

That should be 8 protons since the two gained electrons (purple dots) means that this oxygen ion has 10 electrons (-10 charge) and only 8 protons (+8 charge), giving the ion a net charge of -2.

Answer:

12

Explanation:

+2 charge means there are 2 more protons than electrons in an ion.

If there are 10 electrons, then there are 10+2 protons for a +2 charge.

10+2=12 protons
