Electrostatic forces hold atoms together in molecules—like the two hydrogen atoms. This means it would take about one hundred billion (100,000,000,000) protons. for example, in its elemental state hydrogen exists as a diatomic gas, H2.

Oxygen generally exists as a diatomic molecule in the atmosphere when it is not combined with any other element. It forms the molecule O2 because in that configuration, it has its lowest energy level when uncombined. All substances tend to go to the lowest energy level possible. Oxygen has 6 valence electrons.

Chlorine is counted among this group along with hydrogen (H2), iodine (I2), short of a "stable eight"– the element chlorine exists in nature as a diatomic molecule. List five problems that would arise if chlorine products were unavailable.

Diatomic molecule. Diatomic molecules are molecules composed of only two atoms, of 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.
