Web7 sep. 2024 · Potassium ions have a charge of 1+, while sulfate ions have a charge of 2−. We will need two potassium ions to balance the charge on the sulfate ion, so the proper chemical formula is K 2 SO 4. Calcium ions have a charge of 2+, while nitrate ions have a charge of 1−. We will need two nitrate ions to balance the charge on each calcium ion. WebIn many cases, non-metals form more than one binary compound, so prefixes are used to distinguish them.
