"WebA Lewis base is defined as any species that can donate a pair of electrons, and a Lewis acid is any species that can accept a pair of electrons. All Brønsted–Lowry bases (proton acceptors), such as OH −, H 2 O, and NH 3, are also electron-pair donors. Thus the Lewis definition of acids and bases does not contradict the Brønsted–Lowry definition. " - Does a lewis base donate a proton
