Question

alkaline earth metals are not found in their free state in nature. their electron configurations contain two outer electrons. because they easily give up these two outer electrons, what type of bond do they typically form?
covalent
hydrogen
ionic
metallic

Explanation:

Alkaline earth metals easily give up their two outer electrons. In ionic bonding, one atom donates electrons (like alkaline earth metals donating electrons) and another atom accepts electrons. Covalent bonds involve sharing electrons. Hydrogen bonds are a type of dipole - dipole interaction. Metallic bonds involve a sea of delocalized electrons among metal atoms. Since alkaline earth metals donate electrons, they typically form ionic bonds.

Answer:

C. Ionic
