The Lewis representation above depicts a reaction between a halogen (blue) and a main-group element from group
v (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.
The bonds in the product are
