Explanation:
H . + H . -----> H:H {":" represents a covalent bond, that is, a shared pair of electrons}
A Lewis structure is a convention used to represent the covalent bonding in a molecule. Dots or lines are used to represent
valence electrons (electrons available for bonding). The Lewis structure for the hydrogen molecule is as follows.
H:H or H-H
A bonding pair is an electron pair shared between two atoms.
A nonbonding pair (lone pair, unshared pair) is a pair of electrons that remains on one atom and is not shared.
