How many protons and how many electrons are in an oxygen ion that has a-2 charge? Explanation: A neutral oxygen atom would have 8 electrons. However, the anion has gained two electrons so O2− has 10 electrons. We can also use information about the subatomic particles to determine the identity of an ion.
