Question
To learn how to write ionic formulas. Here are some things to remember when dealing with ionic compounds: By convention, the cation is named first and the anion is named second. A Roman numeral in the name indicates the charge of the cation. The subscripts in the formula represent the number of positive and negative ions that give an overall charge of zero. Consider tin (IV) sulfide. The Roman numeral tells us that the cation has a +4 charge: Sn t. The periodic table tells us that sulfide has a 2 charge: S To balance the +4 charge on tin, we need two sulfide ions: 2(-2) -4. So the formula is written as SnS2 What is the formula for nickel (II) oxide? Express your answer as a chemical formula.
