WebIonic bonds occur when electrons transfer from a metal to a nonmetal. Polar covalent bonds occur between nonmetals that have large differences in electronegativity. The electrons in polar covalent bonds are found on average closer to the more electronegative atom. Nonpolar covalent bonds occur between nonmetals that have small or no ... WebIonic compounds have high melting and boiling points, and they tend to be hard and brittle. Ions can be single atoms, as the sodium and chlorine in common table salt (sodium chloride), or more complex (polyatomic) groups such as the carbonate in calcium carbonate. But to be considered an ion, they must carry a positive or negative charge.
