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?
A)Charge = +2;number of remaining electrons = 8.
B)Charge = -2;number of remaining electrons = 10.
C)Charge = +2;number of remaining electrons = 6.
D)Charge = +2;number of remaining electrons = 2.
