Diatomic molecules (from Greek di- 'two') are molecules composed of only two atoms, of the same or different chemical elements. 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 (N… florsheim orlandoWebThe mass of diatomic hydrogen and the molar gas constant given in Table 1 are from the most recent tabulations of such information [9,10]. The molar mass is given to aid in conversions from molar to mass density. Test points that can be used to verify algorithms based on Eq.
