The octet rule states that main group atoms are most content with eight valence electrons (the electrons that are found in their outermost shells/orbits), the electron configuration of noble gasses. Atoms will behave (and form bonds) in a way to obtain this octet. Covalent bonds occur between two nonmetals. During a covalent bond, the atoms involved share their electrons to reach the desired octet.

八隅體規則 19世紀末,已經有科學家發現配合物是由原子或分子組成,令其組成原子的原子價滿足某條件。1893年阿爾弗雷德·維爾納發現,與中央連接的原子或官能基的數目(「配位數」)通常是4或者6,最高可以是8,不過罕有發生。1904年,阿貝格提出阿貝格規則,指出元素化合價的最大正值和最小負值的相差通常為8。1916年,吉爾伯特·路易斯在其「立方原子理論」制定八隅體規則時就使用了阿貝格規則。
