(a)
Interpretation: The correct chemical formula for a compound formed from potassium and sulfur needs to be determined.
Concept Introduction: The formula of an ionic compound is written in such a way that the symbol for metal is written first, followed by the symbol for non-metal. Also, the number of atoms of each element (metal or non-metal) is written on the subscript of the symbol of the atom of the respective element.
(a)
