Question

Quizplus · Accepted Answer

An ion with 16 protons and 18 electrons would have a net negative charge because there are more electrons than protons. To find the charge, you can subtract the number of protons from the number of electrons: 18 - 16 = 2. Since there are two more electrons than protons, the charge on the ion would be -2.
