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.
The same number as an atom of oxygen. For the most common isotope, oxygen-16, the number is 8, the mass number minus the atomic number.
Consider an atom of oxygen in which the nucleus contains 8 protons and 8 neutrons. If it is doubly ionized, what is the charge of the oxygen ion and how many electrons remain in the ion?
Every atom, ion, and isotope will have 8 protons. The oxygen ion will have 2 more electrons than protons to achieve a full outer shell.
The resulting oxygen ion has a charge of -2.
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.

Every atom, ion, and isotope will have 8 protons. The oxygen ion will have 2 more electrons than protons to achieve a full outer shell.
It has 12 neutrons.

No. An oxyanion is a polyatomic negative ion that contains oxygen. Ammonium is a cation (positive ion) and does not contain oxygen.
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.
There are always 8 protons in Oxygen. This is represented by the atomic number of oxygen. As for electrons , they are often represented by the atomic number in the neutral form, 8, but if the oxygen atom is a ion it would have 10 electrons. For neutrons the average atomic mass is 16.01, neutrons are found by subtracting the number of protons from the atomic mass, so 16.01-8=8.01, there 8.01 average neutrons in oxygen, but in isotopes oxygen can have differnet amounts of neutrons, the mainest is 8 neutrons.
It has a negative charge of -2.
By becoming an oxide ion, O=
No. On its own oxygen is neutral. Its ion, the oxide ion, has a negative charge
Any atom with 8 protons is an oxygen atom. Seven neutrons makes it a particular isotope of oxygen, and nine electrons means that it is an ion, with a charge of minus one. This is unusual because oxygen tends to form ions with a charge of minus two, not minus one, but it isn't impossible.
