All the oxygen isotopes, natural or artificial, has 8 protons, because th atomic number of oxygen is 8.
If your question was 'What is the atomic number of oxygen?', the answer would be 16.
Oxygen's atomic number is 8. Thus, a neutral atom of oxygen will have 8 protons and 8 electrons. The most common isotope of oxygen is 16O, which has 16 - 8 = 8 neutrons.

Oxygen has 8 protons . The number of neutrons depends on the isotope. Oxygen-15 isotope has 7 neutrons and oxygen-16 isotope has 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
That would depend on how many protons exist in the nucleus of the atom. An atom with 6 protons is a carbon atom; 7 protons is nitrogen, and 8 = oxygen.
Oxygen has 8 protons in the atom.
Oxygen's atomic number is 8. Thus, a neutral atom of oxygen will have 8 protons and 8 electrons. The most common isotope of oxygen is 16O, which has 16 - 8 = 8 neutrons.
Oxygen's atomic number is 8. Therefore, it has 8 protons. 16O is its most common isotope, and it has 16 - 8 = 8 neutrons.

O-18 atom has 8 protons, 8 electrons and 10 neutrons.
Each isotope of oxygen (15 to 19) has the same number of protons (8), hence the neutral atoms have 8 electrons.
That would depend on how many protons exist in the nucleus of the atom. An atom with 6 protons is a carbon atom; 7 protons is nitrogen, and 8 = oxygen.
Oxygen has 8 protons in the atom.
8. When an atom becomes an ion, it gains or loses electrons. The number of protons and neutrons doesn't change. If the number of neutrons changes then the atom has changed into a different isotope.
Eight
An atom's atomic number gives its number of protons. Sodium's atomic number is 11. Thus it has 11 protons, regardless of isotope.
