For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. For example, KCl, an ionic compound that contains K⁺ and Cl⁻ ions, is named potassium chloride. video https://cdn.kastatic.org/googleusercontent/F9fhxeAzbl5tczOC_KxI5UnfufCJyVdO9qXgu-Rltqyf00aQlHvx_6KjnT27peERAhBSPipQTUL_5Zz001iLpgdW Naming ions and ionic compounds Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.
