- By calculating the number of va-lence electron shell,we can gain the geometry array of the electronic pair,and then judge the molecular structures. 计算出价层电子对数,得到电子对的几何排布,从而判断出分子的几何构型。
- 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. 另一种理论是路易斯（Lewis）理论（也是在1923年发表）：酸（参阅electrophile）就是能由碱（参阅nucleophile）接受一个电子（electron）对形成一个共价键（covalent bond）的化学物质。
