Fill in the blanks to determine the number of protons and electrons in an oxygen ion. (consult the periodic table to determine the number of protons in a neutral oxygen atom.) the o2− ion has protons and electrons. express your answers as integers separated by a comma.

The protons in an nucleus of an atom will not change unless a nuclear reaction takes place. The number of protons is equal to the atomic number of the element. For a neutral atom, the number of electrons and protons are equal. When they are unequal, then the atom occurs as an ion. It will has a net charge with it. The ion O²⁻ has a net charge of negative positive 2 because it has 2 more electrons than its protons. Since neutral oxygen has 8 protons, then O²⁻ ion has 8 protons and 10 electrons.
