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.
Actually it is iodine dichloride ion (ICl2-) whcih is formed b/w Iodide ion and two chlorine atoms. There are 7 + (2x7) + 1 = 22 valence electrons.The Lewis structure will have a linear geometry with 3 lone pairs are present on Iodine along with two single covalent bonds with chlorine on both sides. [Cl(7 e+e)----I----Cl(7e+e) ]^- Just a rough sketch plz comprehend it. I hope you'll get it. Best wishes!
