An incorrect statement about the alkaline earth metals is: Melting points generally decrease as one descends the group. Densities are less than those of the corresponding alkali elements of the same period. Ionic radii of the M2+ ion increases as one descends the group. The first ionization energy is less than that of the second ionization energy.
