Oxygen isn't always O 2 but can be formed in the upper atmosphere or in some reactions as O 3. Chemists mix and match their terminology somewhat freely when it doesn't matter much, but try to be as specific as possible when it does. O is a singular oxygen atom. O 2 is a molecule made of two oxygen molecules.

Our atmosphere is made of mostly O 2 , which our bodies have evolved to breathe. O is oxygen, while O 2 is dioxygen. Examples of other oxygen molecules are: 0 3 which is ozone trioxygen , there's O 4 that is metastable and is actaully made up of two O 2 molecules tetraoxygen , and O 8 which is a form of pressurised solid O 2 when you freeze O 2 to below around 55 Kelvin and pressurise to around 10 GPa 1. Context is important.

C is the atomic symbol for carbon and can represent not only the element, but one or more atoms of the element, as well as the element as it exists in the understood implied conditions. Same is true for O or N or actually any element. However, elemental O and N are both commonly found as diatomic molecules O 2 and N 2.

I will turn your question around: since oxygen and nitrogen are commonly represented by their ground state chemical compounds at STP why isn't carbon represented by C graphite? The reason is fairly straightforward: it is because the actual compound we have in front of us may be difficult to determine in the case of C or S , while there's generally no question about O 2 or N 2 being the compound we have.

So, we use the atomic symbol to represent the elemental material when it is either of indeterminate or of variable composition. Carbon, in particular, is often found or used as allotropes different than graphite. So we are as specific as we can be, without risking being wrong. If we specify O 2 then sure, there might be some trace amounts of O 3 or even O.

It is much harder to do that with solid elements, so we avoid being too specific remember, as scientists, we should be able to justify our claims, including the nature of the materials we are discussing by using the atomic symbol. Liquid bromine, for instance might be represented as either Br l or Br 2 l although the second is the ground state elemental form at STP.

Symbol of an element only represent one atom of that element. We're doing our best to make sure our content is useful, accurate and safe. If by any chance you spot an inappropriate comment while navigating through our website please use this form to let us know, and we'll take care of it shortly.
