Chromium forms more than one positive ion

WebSince the resulting ion has fewer electrons than protons, the net charge on the ion is positive. The magnitude of the charge is equal to the number of electrons lost, which is equal to the number of valence electrons in the … WebIf they are combined with a one-to-one relationship, this means that chlorine has a charge of -1. To make the compound neutral, copper should have a charge of +1. What follows is that CuCl should be named as copper(I) chloride. Meanwhile, in CuCl2, the two chlorine ions have a charge of -2. Therefore, the copper ion should have a charge of +2.
