The atomic number of oxygen is 8 because oxygen has 8 protons in its nucleus.
The atomic number of a chemical element (also known as its proton number) is always the number of protons found in the nucleus of an atom of that element, and identical to the charge number of the nucleus. It is conventionally represented by the symbol Z.
The Atomic Number is a count of how many Protons are present in an atom of an element.
The element Oxygen has 8 Protons in its atomic nucleus and therefore has an Atomic Number of 8.
Note: in an electrically neutral atom the number of electrons in the electron cloud exactly matches the number of Protons in the nucleus of the atom, therefore electrically neutral oxygen will also have 8 electrons.

What is the atomic number for carbon dioxide?
Carbon Monoxide is a compound with symbols of CO compounds do not have atomic numbers. Carbon is an element with the atomic number 6 oxygen is an element with the atomic number 8
Does carbon dioxide have a atomic number?
Yes, carbon dioxide is a molecule composed of one carbon atom (atomic number 6) and two oxygen atoms (atomic number 8 each).
What is the atomic number for air?
Air is not an element. So it doesn't have an atomic no.It is a mixture of the following gases which have their respective atomic no. given by their side.Nitrogen-7Oxygen-8Carbon dioxide-gas made from carbon-6 and oxygen-8Argon-18
Carbon has an atomic number of 6 how many protons and neutrons are in a nucleus of carbon 13?
Carbon-13 has 6 protons because the element is carbon. Since the atomic number for carbon is 6, it tells us the number of protons. Carbon-13 has 7 neutrons because to get the number of neutrons you subtract the atomic number from the mass number, which is 13.
The number of electrons in phosphate ion?
A phosphate ion (PO4^3-) has a total of 32 electrons. This is because the phosphorus atom contributes 15 electrons (with its atomic number being 15) and each of the four oxygen atoms contributes 6 electrons (since oxygen has 6 electrons each).
