ionic, covalent, metallic

the substance is a good conductor of electricity only when dissolved in water

ionic

the substance typically has low melting and boiling points (often gases, liquids, solids at room temp)

covalent

this bond involves a ‘‘sea’’ of delocalized electrons

metallic

this bond is formed by the complete transfer of electrons from a metal to a nonmetal

ionic

this bond is found in materials that are malleable and ductile

metallic

this type of compound is hard, brittle, and has a very high melting point

ionic

the atoms in this bond share electrons to achieve a stable electron configuration

covalent

this bond is responsible for the excellent electrical and thermal conductivity of certain elements

metallic

what type of bond is found in the compound magnesium chloride (MgCl₂)
