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.
An oxygen ion with a charge of -2 has 8 protons, 10 neutrons, and 10 electrons. The number of protons and neutrons remains the same as a regular oxygen atom (8 and 8, respectively), but the number of electrons increases by two to accommodate the charge.
The total charge on an oxygen ion with 8 protons and 10 electrons is +2, because oxygen normally has 8 protons and 8 electrons, resulting in a neutral charge. Adding 2 extra electrons gives a net charge of -2.
Oxygen becomes negatively charged when it gains two electrons, forming the oxygen ion (O2-). This extra electron results in an excess negative charge, giving the oxygen ion a negative overall charge.
There are 10 neutrons in the ion 18O2. This is calculated by subtracting the atomic number of the oxygen ion (8) from its mass number (18), as neutrons are equal to the difference between these two values.
Li-6 has 3 neutrons and Li-7 has 4 neutrons.

An Mg2+ ion is a magnesium ion that has a charge of +2, meaning it has lost 2 electrons. The number of neutrons in an Mg2+ ion is the same as in a regular magnesium atom, which is 12 neutrons.
The resulting oxygen ion has a charge of -2.
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.
The hydroxyl ion is not a positive ion but rather a negative ion. The hydroxyl ion or anion is also known as hydroxide.
A positively charged ion of oxygen
Li-6 has 3 neutrons and Li-7 has 4 neutrons.
