o What is the net charge of a monatomic ion that has 15 protons, 16 n A 3+ B 2+ C 2- D 3-

To determine the net charge of a monatomic ion, we need to consider the number of protons and neutrons in the nucleus. Protons have a positive charge, while neutrons have no charge.Given that the monatomic ion has 15 protons and 16 neutrons, we can calculate the net charge as follows:1. The number of protons determines the positive charge of the ion. In this case, there are 15 protons, so the positive charge is +15.2. The number of neutrons does not affect the charge of the ion, as they have no charge. Therefore, the net charge remains +15.Therefore, the net charge of the monatomic ion with 15 protons and 16 neutrons is +15.The correct answer is: A
