The hydroxide ion OH- , water H2O, hydronium ion H3O+ , and heavy water H2O2
Water molecule
Any molecule containing oxygen. Any molecule, under the correct conditions, may be split into its component elements, e.g. water (H2O) may be split into hydrogen and oxygen: 2H20 <-> 2H2 + O2 O2 because the natural state of gaseous oxygen is diatomic (i.e. one molecule of oxygen is composed of two oxygen atoms). Exceptions exist, e.g. ozone (O3).
No, the atom is the basic unit for elements. An element consists of one type of atom; iron consists of iron atoms, sulfur consists of sulfur atoms, and so on. A Molecule is a group of atoms of one or more types; carbon dioxide (CO2) is a molecule consisting of one carbon atom and two oxygen atoms, water (H2O) consists of two hydrogen atoms and one oxygen atom. The molecule is the base unit for chemical compounds. A single molecule of water is still the chemical compound water, but if that molecule is split apart into its constituent parts, say through electrolysis, then it ceases to be water and becomes the two elements oxygen and hydrogen. To be thorough, it is important to note that some elements occur naturally in molecular forms. Many gasses occur in molecules consisting of pairs of the same atoms: Hydrogen (H2), Oxygen (O2), Nitrogen (N2), for example. So why isn't the hydrogen molecule the base unit for the element hydrogen? The reason is that if you split the hydrogen molecule into its constituent atoms, those atoms still remain as hydrogen.
Water (H2O) is a molecule with 2 hydrogen atoms and 1 oxygen atom attached by chemical bonds. If we put two electrodes in pure water and apply a DC voltage, the voltage will supply the energy necessary to split water molecules. We call this electrolysis. At one of the electrodes (the positive one), oxygen atoms will appear, and at the other electrode (the negative one), hydrogen atoms will appear.
Oxygen cannot be split into hydrogen.

Since water is comprised of two hydrogen atoms and one oxygen atom, when it is split into atoms by plants during photosynthesis the only other atoms other than oxygen that are produced are hydrogen atoms.
Hydrogen is generally produced by electrolysis of water, where electricity is used to split it into its component atoms: Hydrogen and oxygen

Oxygen and hydrogen are the two ellements that make up water.
when you drink water, the hydrogen and oxygen atoms split and the atoms can be used in the calvin cycle.
Displacement of electrons of the atoms of hydrogen leads to a positive charge on the hydrogen molecule. It can be even split ed off into cations.
Any molecule that contains both hydrogen and oxygen can be split into its component parts. Simple H2O, water, is the simplest. H2O2, hydrogen peroxide, is another example.
