Are H O N and Br diatoms in chemistry?

Answer 1

I think by diatoms you are going for diatomic molecules. The answer is yes. All four (hydrogen, oxygen, nitrogen and bromine) commonly exist as diatomic (molecular) species. Oxygen (O2) and nitrogen (N2) are obviously major components of the atmosphere. Hydrogen (H2) and bromine (Br2) are not found in nature due to their extreme reactivity. Hydrogen atoms are found almost exclusively in water (H2O) and organic matter/petroleum derivatives. Bromine atoms are typically found in the ocean in the form of dissolved salts and in molecules found in marine life. Despite the fact that H2 and Br2 are very rare in nature, they can be synthesized in bulk and made commercially available for manufacturing and research.

Answer 2

No, H, O, N, and Br are not diatomic molecules in chemistry. Diatomic molecules consist of two atoms of the same element bonded together, such as O2 (oxygen) and N2 (nitrogen). These elements can form diatomic molecules, but not as individual atoms.
