3 of the compound
A chemical compound that has a set number of atoms for each element. E.g. water H2O has the fixed ratio of 2:1, that is 2 hydrogen atoms to 1 oxygen atom, carbon dioxide CO2 has a fixed ratio of 1:2 (1 carbon atom to 2 oxygen atoms). It has to be fixed as if it isn't it makes a new compound/chemical.
The elements of a compound are the simplest components that it can be broken down into by chemical means. The atoms of an element have the same number of protons and electrons and have the same behaviors.
The fixed ratio of the elements in a chemical compound is called its RATIO OF MASSES.
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
The chemical formula of the compound shows the ratio of the atoms of elements in a compound. This must not be confused with the ratio of their masses.

You think probable to the chemical formula of a molecule.
If matter is made up of two or more elements and has the same ratio of atoms no matter the amount of the substance it is a compound.
Calcium oxide, CaO: the ratio is 1.
This ratio is different for each compound; for the oxide P4O10 the ratio is 2/5.
