there is only one atom of each element
A chemical compound containing three double bonds is most likely a member of the alkene class of organic compounds. These compounds are unsaturated hydrocarbons with a carbon-carbon double bond. Examples include propyne (C3H4) and but-1,3-diene (C4H6).
A chemical formula would describe a molecule by its constituent parts. The chemical name, however, also is based on chemical formula, and will also describe the molecule.
What you write for an ionic compound is called the formula unit, but the formula unit is almost always the same as the empirical formula. The answer to your question could not be the molecular formula because an ionic compound is not a molecule.

This molecule contain only one atom from each component.
Formulas for compounds do not include oxidation numbers because these numbers are specific to an individual atom within a compound, and the compound as a whole remains neutral. Including oxidation numbers in the formula would imply a charge on the compound, which is not accurate for neutral compounds. The formula provides the ratio of atoms in the compound, while oxidation numbers are used to determine how electrons are distributed in a chemical species.
subscripts
It shows numbers and types of atoms that form the compound.
Compounds formed from X(III) and Z(II) would have the formula X2Z3, while compounds formed from X(V) and Z(III) would have the formula XZ2.
