Diatomic molecules are molecules formed of two atoms, of the same or different chemical elements. The prefix di- means two in Greek. Diatomic elements are those that almost exclusively exist as diatomic molecules, known as homonuclear diatomic molecules in their natural elemental state when they are not chemically bonded with other elements. Examples include H2 and O2. Earth's atmosphere is comprised almost completely (99%) of diatomic molecules which are oxygen (O2) (21%) and nitrogen (N2) (78%). The remaining 1% is predominantly argon (0.9340%)
Oxygen also exists as the triatomic molecule ozone (O3).
The diatomic elements are hydrogen, nitrogen, oxygen, and the halogens: fluorine, chlorine, bromine, iodine, and astatine. Astatine is so rare in nature (its most stable isotope has a half-life of only 8.1 hours) that it is usually not considered. Many metals are also diatomic when in their gaseous states.
The bond in a homonuclear diatomic molecule is non polar and fully covalent. Examples of heteronuclear diatomic molecules include carbon monoxide (CO) and nitric oxide (NO).
Other elements exist which form diatomic molecules but with high instability and reactivity. An example is diphosphorus.

Right Gemma I will not give you the answer but how to find them Put this string into Google with the quotes and without them.

If you have a search eng. like Google, search for diatomic molecules in Wikipedia. It's all there!

In addition to the stuff above, remember that most gases are diatomic.

Look at the periodical table. Find where oxygen is on the table and look at the other elements on the same up and down column.

Hydrogen is diatomic because it exists as a molecule. i.e H2.....ita all bout bonding(covalent)......Ozone is triatomic i.e. O3....er...hope this helps!

only think of how fortunate you're to have lots hair & comprehend you likely continuously will, in assessment to three people balding oldies. All we are able to do is shave it & desire we appear like Bruce Willis!
