双原子分子

维基百科,自由的百科全书

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(包括等)的单质均是双原子分子。其他元素(如)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,的同核双原子分子占地球大气层成分的 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

金属元素和其他非金属元素的双原子分子

金属元素和其他非金属元素在气态可能是双原子分子,但较罕见。 例子有(Li2)、(Ne2)、(Na2[1](P2)、(S2)、Ar2)、(Cr2)、Rb2)、(Mo2)、(W2)、(At2)和(U2)。

其中,的双原子分子是以六重键存在。
