How would you answer this simple chemistry question?
Compare and contrast ionic and molecular compounds in terms of electrical
conductivity, melting and boiling points.
covalently bonded molecular compounds tend to have low boiling and melting points and not conduct,
ionically bonded compounds will dissociate in water so will conduct in solution or molten. They tend to have high boiling and melting points.
both have made the single elements more stable in the compound form by filling electron energy levels.
