WebA chlorine atom has a total of 17 electrons with 7 electrons in its valence shell. When these two atoms meet the lone valence electron of sodium is transferred to the chlorine atoms and both atoms end up with their valence shells complete. The electron transfer between the two atoms moves one unity of negative charge from sodium to chlorine. WebChlorine has seven electrons in its last orbit. In this case, the chlorine atom can receive electrons in its last shell. Atomic number, atomic weight and charge of chloride ion (Cl –) …
