Web27 apr. 2024 · Diatomic elements are all gases, and they form molecules because they don’t have full valence shells on their own. The diatomic elements are: Bromine, Iodine, Nitrogen,Chlorine, Hydrogen, Oxygen, and Fluorine. Ways to remember them are: BrINClHOF and Have No Fear Of Ice Cold Beer. WebA molecule of hydrogen is formed by the combination of two atoms of hydrogen with one electron each present in the 1s orbital. hydrogen (1s 1) has one electron less than the stable inert gas configuration (He;1s 2) and therefore it shares its single electron with an electron of another hydrogen atom to form a stable diatomic molecule. Thus two …
