An Ionic compound is any compound in which some of the atoms gain or lose electrons to form Ions, and it has no specific state (solid, liquid, gas). So, the short answer is no, not necessarily.
"an is an ionic"
"Better" depends on the context. For some purposes solid may be better, for others, melted will be better.
A melting ionic compound allows ions to move freely within the liquid, increasing conductivity. In contrast, in a solid ionic compound, ions are fixed in a lattice structure and cannot move as easily, reducing conductivity.
yes, it is an ionic compound and all ionic compounds exist in solid state.
It is an ionic crystalline solid
Table salt, which is sodium chloride, is an ionic compound.
Ionic compounds are conductors in solution or melted.
An ionic compound always exists in solid state.
ionic compounds are a metal and a non-metal joined together in a bond
