Question

If an ion has 35 protons and 36 electrons what is the charge on the ion

Answer 1

Since there are 35 protons in the nucleus and each proton carries a charge of +1, the charge on the nucleus is +35. The 36 electrons, each with a charge of -1, combine to give a charge of -36. The net charge on the ion is the difference between the two: Ion charge = +35 - 36 = -1.
