WebOn the left, the chlorine atom has 17 electrons. On the right, the chloride ion has 18 electrons and has a 1− charge. With two oppositely charged ions, there is an electrostatic attraction between them because opposite charges attract. The resulting combination is the compound sodium chloride. Notice that there are no leftover electrons. WebA) is filled when it has three electrons. B) determines its chemical reactivity. C) determines its atomic mass.
