Which type of chemical bond shares one or more pairs of electrons between nuclei?

A covalent bond is a chemical bond that shares one or more pairs of electrons between nuclei. An ionic bond is a chemical bond that has a relatively weak attraction between an anion and a cation. A hydrogen bond is a chemical bond that has a weak attraction between polarized molecules. A Van der Waals bond is a chemical bond that has a weak attraction due to random disturbances in the electron clouds of adjacent atoms; it is also the weakest of all bonds.
