What is the charge of an Ion that has 12 protons and 13 electrons

• -2

• +2

• -1

• +1

Answer explanation

The difference between protons and electrons determines the charge.

Example: if there is 1 proton and 2 electrons, then the difference is 1.

Since electrons outweigh protons then it is a negative charge.
