8 protons
A neutral oxygen atom usually has 8 protons and 8 electrons. In oxygen-18 isotope, the number of protons remain the same (8), but the number of neutrons is increased to 10, making it oxygen-18. So, a neutral oxygen-18 atom would still have 8 electrons.
There are 8 electrons in a single neutral oxygen atom.The atomic number of oxygen is 8, because it has 8 protons in its nucleus. In an elemental, neutral, atom of oxygen the number of electrons will match the number of protons. There are 8 electrons in a neutral oxygen atom.Note that oxygen can become an ion under certain circumstances, and we need to specify the neutral atom to state how many electrons there are in oxygen.
Oxygen's atomic number is 8. Thus it has 8 positively charged protons per atom. In order for oxygen to be neutral, it must also have 8 negatively charged electrons in each 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.

An atom of chlorine has 17 protons.
Oxygen has 8 protons and 8 electrons in its atom.
protons
The atom must have 8 electrons to make it have a neutral charge
If a neutral atom of sodium has 11 protons, it will have 11 electrons also.
A neutral atom with 12 protons will have 12 electrons in order to balance the positive charge from the protons.
The number of electrons should = the number of protons.
