Which statement best describes ionic bonding?

A. Electrons are free to move among many atoms.

B. Electrons are taken away from a full valence shell.

C. Electrons are shared between two atoms.

D. Electrons are transferred from one atom to another.

D. Ionic bonding is when electrons are transferred. When they're shared, it is covalent. In order to take an electron from a full valence electeon shell, you would need a massive amount of energy.

Electrons are transferred from one atom to another describes ionic bonding.

Option D

Explanation:

Ionic bonding requires at least one acceptor and one donor. ''Ionic bond'' is the movement of ''valence electrons'' between atoms. It gives two oppositely charged ions after taking place. The metal loses electrons and form a positive cation, and non metals gains electrons to become negative cations. Thus electron donor is a metal, and electron acceptor is usually a non metal. Thus, it is evident that in ionic bonding electrons are transferred between atoms.
