An oxygen atom contains eight electrons, arranged into two orbital shells. Electron Situated within the two shells, these subatomic particles have a mass of almost zero and a charge of -1. Unpaired electron Two electrons in the outer shell don’t have a partner. This allows oxygen atoms to ...
O is a free oxygen atomand O2 is two oxygen atoms chemically bound to form an oxygen molecule. There is no common analogy for C, but N2 is called nitrogen, H2 is hydrogen and Cl2 is chlorine, each having the same name as that of their constituent elements. ...
