a. ionic
b.ionic or metallic
c.metallic
d. covalent network
e. ionic or covalent network

The answer is (e) ionic or covalent network, but my question is does someone have a way to remember all of these solids and what they do with regard to boiling point, melting point, conductivity, and bond strength?

Answer 1

Try to remember them by common examples.

covalent network solid: diamond
ionic solid: sodium chloride (table salt)
metallic solid: copper

Answer 2

Ahh okay, yeah that sounds easy to remember....Thanks again Adastra!!
