Detailed Solution

Reaction between X and Y, forms compound Z. X loses electrons and Y gains electrons. Property of a low melting point is not shown by Z.
Metals which lose electrons are called electropositive metal. According to question X loses an electron so it is an electropositive metal. Non-metals gain an electron so according to question Y is a Non-Metals as it gains an electron. Ionic compound is formed when a metal and a Non-Metals react among themselves. Usually, ionic compounds have high melting points and in their molten state they are good conductors of electricity. Also, these compounds are solids.
