The compound, A2Z3, is a made-up compound. If this is an ionic compound, name two elements that A & Z may be?

Hello!

If A₂Z₃ is an ionic compound, the ions that form it would be A⁺³ and Z⁻².

The atoms that can form A⁺³ ions are in the 13th group of the periodic table, so two elements that can be A are Aluminum (Al) and Galium (Ga).

The atoms that can form Z⁻² ions are in the 16th group of the periodic table, so two elements that can be Z are Oxygen (O) and Sulfur (S).

Al₂O₃ (Aluminum Oxide) is an example of an A₂Z₃ compound

Have a nice day!
