Question 1

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.
◦ The first ionization energy is less than that of the second ionization energy.
◦ Ionic radii of the M2+ ion increases as one descends the group.

Question 2

Which is not generally considered to be a chemical reaction of the alkaline earth metal calcium?
◦ Ca(s) + O2(g) → CaO2(s)
◦ 2 Ca(s) + 2 H2O(l) → 2 Ca(OH)2(aq) + H2(g)
◦ 6 Ca(s) + 2 N2(g) → 2 Ca3N2(s)
◦ Ca(s) + Cl2(g) → CaCl2(s)
