Answer 1

A particular solid is very hard and has a high melting point. In solid state, it is a non-conductor and in molten state, it is a conductor of electricity. Classify the solid Ionic.

Explanation:

A certain substance has a high melting point and is exceedingly hard. It is a non-conductor while it is solid and a conductor of electricity when it is molten. It is an ionic solid as a result.
