An element can combine with one or more other elements to form compounds, of which there are millions. For example, one of the best known compounds is water, written chemically as H 2 0, which means that water is made of two atoms of hydrogen chemically bonded to one of oxygen.
These elements can often be found to occur in nature and include isotopes of carbon, nitrogen, hydrogen, oxygen, noble gases and metals. For example, there are a lot of carbon atoms in the universe. The normal ones are carbon-12.
So water is an example of an element. In all pure water, there are two parts of hydrogen to one part of oxygen. Similarly, carbon dioxide fits the criteria for being a compound.
Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes. An atom is first identified and labeled according to the number of protons in its nucleus.

The atomic number of an element is equal to the number of protons in each atom, and defines the element. For example, all carbon atoms contain 6 protons in their atomic nucleus; so the atomic number of carbon is 6. Carbon atoms may have different numbers of neutrons; atoms of the same element having different numbers of neutrons are known as isotopes of the element.

Elements and the ‘Big Bang’ theory. During the formation of the universe some 14 billion years ago in the so-called ‘Big Bang’, only the lightest elements were formed hydrogen and helium along with trace amounts of lithium and beryllium. As the cloud of cosmic dust and gases from the Big Bang cooled, stars formed, and these then grouped together to form galaxies.
