7.3 Molecular Polarity and Dipole Moments
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 … See more All other diatomic molecules are chemical compounds of two different elements. Many elements can combine to form heteronuclear diatomic molecules, depending on temperature and pressure. Examples are gases See more Hundreds of diatomic molecules have been identified in the environment of the Earth, in the laboratory, and in interstellar space. About 99% of the Earth's atmosphere is … See more Diatomic molecules are normally in their lowest or ground state, which conventionally is also known as the $${\displaystyle X}$$ state. When a gas of diatomic molecules … See more The molecular term symbol is a shorthand expression of the angular momenta that characterize the electronic quantum states of a diatomic … See more All diatomic molecules are linear and characterized by a single parameter which is the bond length or distance between the two atoms. … See more Diatomic elements played an important role in the elucidation of the concepts of element, atom, and molecule in the 19th century, because some of the most common elements, such as hydrogen, oxygen, and nitrogen, occur as diatomic molecules. See more The good quantum numbers for a diatomic molecule, as well as good approximations of rotational energy levels, can be obtained by modeling the molecule using Hund's cases.
