'Formula' only comes in (in a meaningful way) for molecules.

Well, you didn't indicate the atom so I'll do what I can. The formula for acetic acid is CH3COOH. If the indicated letter in the formula is C, the atom is carbon. If the indicated letter in the formula is H, the atom is hydrogen. If the indicated letter in the formula is O, the atom is hydrogen.
The chemical formula for sodium hypochlorite is NaOCl, consisting of one sodium atom, one oxygen atom, and one chlorine atom.
There is one atom of carbon in this formula. The formula indicates one atom of Copper + one atom of Carbon + 3 atoms of oxygen. O3 added to any compound prompts the suffix -ate, so in this case, you have a formula for Copper Carbonate.
