Question

Which crystalline solid are very good conductor ​

Answer 1

Required Answer:

☑ Carbon atoms are arranged in different layers and each atom is covalently bonded to three of its neighbouring atoms in the same layer. The fourth valence electron of each atom is present between the different layers and is free to move about. These free electrons make graphite a good conductor of electricity.

Answer 2

For example, graphite has a relatively high electrical conductivity within the carbon planes, and diamond has the highest thermal conductivity of any known substance. Classify Ge, RbI, C6(CH3)6, and Zn as ionic, molecular, covalent, or metallic solids and arrange them in order of increasing melting points.
