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.
Time for an atom lesson: Chlorine is number 17 on the Periodic Table, which means it has 17 protons. Chlorine-37 has 37 total protons and ne â¦ utrons (that is not a coincidence-- Carbon-12 has 12 total, Hydrogen-1 has 1 total, etc.). The rest is simple math- 37 total minus 17 protons equals 20 neutrons.
