双原子分子

双原子分子指所有由两个原子组成的分子。双原子分子内的化学键通常是共价键。

很多非金属元素(包括氢、氮、氧、氟、氯、溴、碘等)的单质均是双原子分子。其他元素(如磷)也可能以双原子分子构成单质,但这些双原子分子并不稳定。这些构成单质的双原子分子称为同核双原子分子。其中,氮和氧的同核双原子分子占地球大气层成份的 99%。

以双原子分子存在的化合物包括一氧化碳、一氧化氮、氯化氢等。这些双原子分子称为异核双原子分子

Diatomic molecules are molecules composed of only two atoms, of either the same or different chemical elements. The prefix di- is of Greek origin, meaning "two". If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H2) or oxygen (O2), then it is said to be homonuclear. Otherwise, if a diatomic molecule consists of two different atoms, such as carbon monoxide (CO) or nitric oxide (NO), the molecule is said to be heteronuclear.
