Another is the Lewis definition (also 1923): An acid (see electrophile) is a chemical that can accept an electron pair from a base (see nucleophile), which they share to form a covalent bond. 另一種理論是路易斯（Lewis）理論（也是在1923年發(fā)表）：酸（參閱electrophile）就是能由堿（參閱nucleophile）接受一個電子（electron）對形成一個共價(jià)鍵（covalent bond）的化學(xué)物質(zhì)。
