# Strongest bond in chemistry

Strongest bond in chemistry ionic ,covalent or metallic?Bond strength decrease in the following order covalent > ionic > metallic so i think strongest bond would be covalent bonding then comes ionic bonding and at last metallic bonding.Correct me if i am wrong.One more question is water/ice molecular solid or covalent solid ?My teacher says there is nothing separate type of solid called covalent solid .(According to my teacher metallic solid is same as covalent solid.)instead there is covalent network solid. I think covalent solid and covalent network solid is same thing ,they differ from metallic solid due to a fact that in metallic solid there are atoms of metal on each crystal lattice point but in covalent solid or covalent network solid there are atoms but of nonmetals on each lattice point. especially of carbon.Am i right?in molecular solid (crystal) there are molecules on each crystal lattice point,so water should be molecular solid.
