Need to be classified elemental Boron as one of the crystalline solid on the basis of following properties: high melting point (2300 о C), poor conductor of heat and electricity, insoluble in water, and very hard Concept Introduction: Crystalsare classified into various types as follows: Ionic, covalent, metallic, and molecular crystal. The type of crystal in which the solid is hard, brittle, and non-conducting in nature is known as ionic solid. It conducts electricity in aqueous solution. They have usually high melting points. The type of crystal in which the solid is very hard and a poor conductor is known as covalent solid. It does not conduct electricity in the solid state as well as in aqueous solution. Theyusually have high melting points. They have covalent bonds.
