Question

the chemical formula for an ionic compound made of potassium and chlorine is kcl. what is its chemical name?
potassium oxide
potassium chlorine
potassium chloride
potassium anion

Explanation:

For ionic compounds, the naming rule is to name the cation (positive ion) first, then the anion (negative ion) with its ending changed to -ide. Here, the cation is potassium (K⁺) and the anion is chloride (Cl⁻, chlorine's anion form). Potassium oxide would involve oxygen (O), potassium chlorine is an incorrect naming as the anion form should have -ide ending, and potassium anion is a wrong concept as potassium forms a cation (K⁺).

Answer:

potassium chloride
