Answer

Brief Explanations:

To form a neutral compound, the total positive and negative charges must balance. Potassium has a +1 charge and sulfur has a -2 charge. So, two potassium ions are needed for each sulfur ion to balance the charges, giving the formula K₂S. In naming ionic compounds, the metal (potassium) is named first, followed by the non - metal with its ending changed to -ide (sulfide).

Answer:

The chemical formula is K₂S, and the name is potassium sulfide.
