Detailed explanation-1: -Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus. Oxygen is a gas at room temperature and has no colour, smell or taste.

Detailed explanation-2: -Oxygen is group 8 element, so, the atom of oxygen has 8 protons and 8 electrons. The ion has the same number of protons because you never lose a proton to make an ion. But in the case of oxide form, it carries two negative charges. Negative charge come due to the transfer of electron.

Detailed explanation-3: -The number of protons an atom has is called its Atomic Number. The atomic number of carbon is 6 because carbon atoms have 6 protons. The atomic number of oxygen is 8 because oxygen atoms have 8 protons in their nucleus.

Detailed explanation-4: -Oxygen atom has 8 electrons, 8 protons and 8 neutrons.

Detailed explanation-5: -The atomic number of oxygen is 8. The mass of an atom is given by the sum of the number of protons and neutrons present in the nucleus. Also, the atomic number is the number of protons present in the nucleus. Since the number of neutrons present in oxygen is 8, hence the atomic number of O is 8.
