In one Molecule of water there are two hydrogen atoms and one oxygen atom
One molecule of water contains 2 atoms of Hydrogen - and 1 atom of Oxygen.
There are three atoms in a molecule of water. One oxygen atom and 2 hydrogen atoms. The simplified form for the molecule of water is H2O which is a coded form for the 2 hydrogen and 1 oxygen atoms that make up the molecule.
H2OCount two atoms hydrogen in one molecule of water.
Water or H2O has exactly the number of atoms listed in each molecule: two hydrogen and one oxygen.
One.
In one Molecule of water there are two hydrogen atoms and one oxygen atom
There is one water molecule in H2O
One molecule of water contains 2 atoms of Hydrogen - and 1 atom of Oxygen.
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
two
This is one atom of oxygen in a molecule of water. There are two atoms of hydrogen in that same molecule.
The chemical formula for water is H2O. The subscripted "2" indicates that there are two atoms of hydrogen in one water molecule. No subcripted number means there is just one atom in the molecule, meaning there are two hydrogen atoms and one oxygen atom.
