Oxygen has an atomic number of 8, which means it has 8 protons. Given a neutrally charged atom, the atomic number will be equal to the number of electrons, so again, there are 8 electrons.
Ionized oxygen, which is still the same element, has gained or lost electrons such that it has a net positive charge (more protons than electrons) or negative charge (more electrons than protons).
The primary isotope of oxygen, Oxygen-16 (that number being the sum of protons and neutrons), also has 8 neutrons.
Rarer isotopes have fewer or greater numbers of neutrons with the same number of protons, but for the purposes of your question, 8 neutrons is the answer.
Oxygen has 8 electrons and protons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the isotope - Number of protons
8
Oxygen has 8 protons, 8 electrons, and typically 8 neutrons in its nucleus.
8 protons and 9 neutrons (total is the atomic mass number 17). In a neutral atom, 8 electrons. Oxygen-17 is the rarest of the three stable natural isotopes. Most oxygen is oxygen-16 with 8 neutrons.
A hydrogen atom typically has one proton and one electron, with no neutrons in its most common isotope. An oxygen atom has eight protons, eight electrons, and usually eight neutrons, though there are isotopes of oxygen that may have different numbers of neutrons.
An oxygen atom has 8 protons, 8 electrons, and either 8 or 9 neutrons, depending on the isotope.
Oxygen has 8 electrons and protons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the isotope - Number of protons
Oxygen has: 8 neutrons 8 protons (8 electrons)

An oxygen-16 atom has 8 protons, 8 neutrons, and 8 electrons. This is because the atomic number of oxygen is 8, which defines the number of protons and electrons, and the atomic mass is 16, which includes both protons and neutrons.
Oxygen has 8 protons, 8 electrons, and typically 8 neutrons in its nucleus.
8 protons, 8 electrons, 8 neutrons in oxygen
18 protons 18 electrons 22 neutrons
8 since the atomic number equals the number of protons!!
A negative 2 charge means that the oxygen is richer in two electrons. The configuration of oxygen is: 1s22s22p4 and we can conclude that it has 8 electrons. For the atom to be neutral the amount of protons must be the same. Oxygen atom has 8 neutrons. Let's add the two electrons to the eight, so the oxygen will be on negative 2 charge. To summarize, the amount of electrons - 10, protons- 8, neutrons - 8.
8 protons and 9 neutrons (total is the atomic mass number 17). In a neutral atom, 8 electrons. Oxygen-17 is the rarest of the three stable natural isotopes. Most oxygen is oxygen-16 with 8 neutrons.
Aluminum has 13 electrons/protons and 14 neutrons.
