** + The Lewis representation above depicts a reaction between a halogen (blue) and a main-group element from group 9 (red). In this representation, each Y atom needs electron(s) to complete its octet, and gains these electrons by forming bond(s) with atoms of X. There are unshared electron pair(s) and bonding electron pair(s) in the product molecule.
