Answer:
Ionic solid
Explanation:
Ionic solids -
These are the type of solids , which is composed of ions , which are bond by very strong electrostatic force of attraction , are referred to as ionic solids.
And due to very strong force of attraction between the ions , they generally have very high melting point.
When the solid is dissolved in water , the ions gets separate out , and these free ions are capable to conduct electricity , and hence they are very good conductor in molten form , and are insulator in solid form.
Hence , from the given information of the question ,
The correct term is ionic solids.
