An iron ion contains 26 protons, 27 neutrons, and 23 electrons. What is the net charge of the ion?

Take the total protons and subtract that number from the total electrons (neutrons are exempt because they have no charge). You then have the number 3 and multiply that by the elementary constant 1.60 x 10 -19. The answer is 4.8 x 10-19

To determine the net charge of an ion, we need to compare the number of protons (positive charge) and electrons (negative charge). In a neutral atom, the number of protons is equal to the number of electrons. However, in an ion, the number of electrons can be different from the number of protons, resulting in a net charge.

In this case, an iron ion has 26 protons and 23 electrons. Since protons have a positive charge and electrons have a negative charge, the ion has a net charge equal to the difference between the number of protons and electrons. Therefore, the net charge of the iron ion is +3 (26 protons - 23 electrons = +3).
