Do nonmetals have high or low melting points? Do nonmetals have high or low boiling points? Do metals or nonmetals tend to form positive ions? Does oxygen have a higher electronegativity than hydrogen? Do nonmetals have luster? Are nonmetals reactive?
Why do ionic compounds have high melting points? Explain why covalently bonded materials are generally less dense than ionically or metallic bonded materials. Why are termolecular steps infrequently seen in chemical reactions? Why do zinc and lead nitrate to react? Why do impure mole...
High melting points brittle solids nonconducting as solids conduct electricity as liquids or aqueous Ionic Compounds As solids, exist in a 3-D repeating pattern called a crystal “lattice” the lattice energy is the energy lowering accomplished by the formation from free ions ...
