An Allegory is used to tell a story that has characters, a setting, as well as other types of symbols, that have both literal and figurative meanings.
Chlorine is counted among this group along with hydrogen (H 2), iodine (I 2), bromine (Br 2), oxygen (O 2), nitrogen (N 2) and fluorine (Fl 2). With seven electrons in its outermost orbit--one electron short of a stable eight-- the element chlorine exists in nature as a diatomic molecule. This arrangement allows two chlorine atoms to share their outermost orbit electrons, achieving stability, compared to the single atom.
But on the other hand an atom is a neutral species therefore have no charge on them. There is a huge difference between a chlorine atom and a chloride ion. Chlorine atom is a neutral species and has no charge on it. A chlorine atom has an atomic number of 17. It's electronic configuration can be given as:-.
