Answer
You can determine the total amount of electrons that go into a Lewis diagram of an ion by counting and adding up the number of valence electrons of every atom, as well as the charge on the ion. For example, if the ion has a positive charge of 2, it would be correct to subtract 2 from the total valence electron count. If the charge is negative 1, you should add an electron to the total.
