Question

what is the name of the binary compound for the formula ki?
move the correct answers to the box.

Explanation:

Step1: Identify the ions

K (potassium) is a Group 1 metal, so it forms \( K^+ \) ions. I (iodine) is a Group 17 non - metal, so it forms \( I^- \) ions.

Step2: Name the compound

For binary ionic compounds (composed of a metal and a non - metal), we use the name of the metal followed by the name of the non - metal with the ending changed to -ide. So, potassium (K) and iodine (I) form potassium iodide.

Answer:

potassium iodide
