Question

which statement best describes how an ionic bond forms?
the transfer of electrons forms strong bonds between ions.
the sharing of electrons forms strong bonds between ions.
the transfer of electrons results in repulsive forces between molecules.
the sharing of electrons results in attractive forces between molecules.

Explanation:

Ionic bonds form when one atom donates electrons (becomes a cation) and another atom accepts those electrons (becomes an anion). The resulting positive and negative ions are attracted to each other, creating a strong bond. Sharing of electrons is characteristic of covalent bonds, not ionic bonds. Repulsive forces between molecules are not related to ionic - bond formation, and attractive forces between molecules due to electron - sharing are also not relevant to ionic bonds.

Answer:

The transfer of electrons forms strong bonds between ions.
