Question

How do you determine the charge of an isotope?

Answer 1

Answer:

If the protons in the atom outnumber the  electrons, the isotope has more positive charges than negative charges but If the number of electrons exceeds the number of protons, the ion charge will be negative.

Explanation:

Answer 2

The charge of an isotope is defined by how many more protons there are than electrons.

Or the other way around.

For example if there are 4 protons and 2 electrons, the ion charge is +2 because there are more protons.

If there are 4 electrons and 2 protons, the ion charge is -2 because there are more electrons.
