19 Σεπ 2022 · The charge of the metal ion is determined from the formula of the compound and the charge of the anion. For example, consider binary ionic compounds of iron and chlorine. Iron typically exhibits a charge of either 2+ or 3+ (see [link]), and the two corresponding compound formulas are FeCl 2 and FeCl 3.
17 Σεπ 2020 · Here is a chart of element charges and an explanation of how to find the charge of an element if you don’t know it. The difference between charge, oxidation state, and valence is explained, too. You can download and print these graphics and tables for references.
Roman numeral notation indicates charge of ion when element commonly forms more than one ion. For example, iron( II ) has a 2+ charge; iron( III ) a 3+ charge.
