Which term describes an electron pair acceptor?

Explanation:
In Lewis theory, an electron pair acceptor is called a Lewis acid. The basic idea is that acids accept electron density from bases, which donate a lone pair to form a bond. For example, a proton (H+) can accept an electron pair from a donor like ammonia to create a coordinate bond, and metal ions such as Al3+ accept lone pairs from ligands like water or ammonia. This plus the counterpart, a Lewis base, which donates an electron pair, makes the framework clear. Arrhenius acids relate to increasing H+ in water, and Brønsted-Lowry bases are proton acceptors, which are related concepts but describe different aspects of acid–base behavior. The term that directly describes an electron pair acceptor is Lewis acid.
