The oxygen combines with haemoglobin (US English: hemoglobin) to form Oxyhaemoglobin.
Its atoms are rearranged along with glucose molecules to make carbon dioxide and water.
the atmosphere
2 Oxygen atoms
Oxygen in the air is composed of molecules which are each made up of two oxygen atoms. An oxygen atom contains protons and neutrons in its nucleus, 8 of each being the most usual form (some variation in the number of neutrons does exist) and it has 8 electrons orbiting the nucleus (2 in the inner shell, 6 in the outer shell).
A molecule made up of three atoms of oxygen is Ozone which is O3.
Water is a compound. A molecule of water is made up of two hydrogen atoms and one oxygen atoms. Oxygen and hydrogen are both elements. Water is a compound. A molecule of water is made up of two hydrogen atoms and one oxygen atoms. Oxygen and hydrogen are both elements.
A molecule of water, which has the formula H2O, is made up of the elements hydrogen and oxygen.
The oxygen that we breathe has 2 oxygen atoms in each molecule. Ozone has 3 oxygen atoms in each molecule which makes it a more powerfully oxidizing form, decaying to normal O2 in the process.
We breathe oxygen. It is a substance in the air, we breathe in oxygen and breathe out a small percent of oxygen and carbon dioxide. Plants and trees use carbon dioxide and produce oxygen, thank god for them, or we would be dead. Oxygen also makes up a part of water, one molecule oxygen, to hydrogen. Hope I helped.
An ozone molecule has 3 atoms of oxygen (O3), compared to the two-atom molecule (O2) that we breathe.
If you recall from basis chemistry, water is made up of 2 hydrogens and 1 oxygen. The reason why we can't breathe underwater is because the oxygen molecule is already bound to the hydrogen molecules. Oxygen in this form is useless to our lungs. Our lungs can't extract oxygen from water
There is one element, oxygen, in ozone. Each molecule of ozone contains three atoms of oxygen.
Animals do not use up all the oxygen in the atmosphere because plants produce oxygen. When they breathe, plants inhale carbon dioxide (which is what animals breathe out) and exhale oxygen (which is what animals breathe in).

O2 is the molecule Oxygen (O) is an element and is diatomic, which means it will naturally pair up.
Oxygen
Oxygen is made up of two oxygen atoms (O=O), and ozone is made up of three (O-O=O).
