Question

how do ionic bonds form?
a atoms of metallic elements give up electrons to atoms of nonmetallic elements
b atoms of nonmetallic elements give up electrons to atoms of metallic elements
c atoms of metallic elements accept electrons from atoms of nonmetallic elements
d two of the above

Explanation:

Ionic bonds form when atoms of metallic elements (which have low ionization energies) give up electrons. These electrons are then accepted by atoms of non - metallic elements (which have high electron affinities). This transfer of electrons creates positively charged metal ions (cations) and negatively charged non - metal ions (anions). The electrostatic attraction between these oppositely charged ions forms the ionic bond.

Answer:

A. atoms of metallic elements give up electrons to atoms of nonmetallic elements
