2 hydrogen atoms and 1 oxygen atom
To determine the number of each kind of atom in a molecule of a compound, you need to refer to its chemical formula. The formula indicates the types of atoms present and their quantities, for example, in water (H₂O), there are two hydrogen atoms and one oxygen atom. If you provide a specific compound, I can give you the exact count for that molecule.
There are two atoms of hydrogen and one atom of oxygen in one molecule of water.
Water or H2O has exactly the number of atoms listed in each molecule: two hydrogen and one oxygen.

elements
The smallest whole bit of matter for elements is an atom, for compounds is a molecule, and for mixtures is a particle.
1 Carbon atom and 2 Oxygen atoms. The formula is CO2, which means that there are one atom of carbon and two atoms of oxygen in one molecule. The subscripts tell you the numbers of each element. No number is understood to be one.
