How to write a formula for sodium and sulfur?
Write the formula for sodium combined with sulfur. 1. Write the symbol and charge of the cation (metal) first and the anion (nonmetal) second. 2. Transpose only the number of the positive charge to become the subscript of the anion and the number only of the negative charge to become the subscript of the cation.
What is the chemical formula for potassium and sulfate?
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.
Which is the correct formula for sodium chloride?
