Lewis formula

The Lewis formula is the structural formula of a molecular species in which all the electrons of the valence shell are represented by points placed in such a way that two points represent an electron pair or a single covalent bond between two atoms.

Note:

1. A double bond is represented by two pairs of points and a triple bond by three pairs.

2. For the sake of simplicity, electron pairs are often represented by a dash.
