8
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.
It needs 2 electrons for this. Oxygen makes -2 ion by gaining 2 electrons. It is the most stable ion that oxygen makes.
The oxygen atom would have a charge of -2 after gaining two electrons to become an oxygen ion.
The resulting oxygen ion has a charge of -2.
An oxygen atom has 6 protons and 6 electrons, giving it a neutral charge. When it gains 2 electrons to form an oxygen ion, it will have 8 electrons in total. Since it now has 2 more negatively charged electrons than positively charged protons, the oxygen ion will have a charge of -2.

There are 16 electrons in this ion. 7 from nitrogen, 8 from oxygen and the other one is from the ionic charge.
There are 2 electrons in an oxygen ion with a charge of -2. This is because oxygen normally has 6 electrons, but when it gains 2 extra electrons to become an ion with a charge of -2, it now has 8 electrons total.
Sulfur typically gains 2 electrons to form an ion with a -2 charge.
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.
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.
Oxygen will tend to gain 2 electrons to form an ion with a charge of -2. This is because oxygen has 6 valence electrons and is looking to achieve a stable octet configuration like the nearest noble gas, which has 8 valence electrons.
