A sodium atom contains 11 protons and 11 electrons. A chlorine atom contains 17 protons and 17 electrons. What must occur for a sodium atom to obtain a charge of 1+ and a chlorine atom of 1-? A.
The sodium atom remains unchanged while the chlorine atom must gain one electron.
B.
The sodium atom must lose one electron while the chlorine atom remains unchanged.
C.
Neither atom must gain or lose electrons because the chlorine atom already has a charge of 1- and the sodium atom already has a charge of 1+.
D.
The sodium atom must lose one electron to the chlorine atom, which gains one electron.
