Answer 2

Answer: Carbon and Oxygen

The symbols refer to the two elements Carbon and Oxygen, respectively. These elementary atoms form molecules by bonding to each other. Due to the atomic properties of these two elements, one of the most stable configurations C and O tend to form is a molecule that contains 2 Oxygen atoms for one atom of Carbon, hence the number "2" attached to the symbol O.
