The lewis representation above depicts a reaction between a halogen (blue) and a main-group element from group (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

a galvanic cell( aka voltaic cell) and electrolytic cell
