Question

1. Elements Q and S react together to form an ionic compound. Under normal conditions, which physical state will the compound QS exist in?
2. Can Q and S, both be metals? Justify your answer.

Answer 1

1.  As QS is an ionic compound, it consists of ions bonded tightly together by strong electrostatic forces between them. Due to this, it is a hard solid.
2. No, Q and S can’t both be metals because they react to form an ionic compound. This is only possible when one is a metal and the other is a non-metal.
