pan electrons, multiple bonds, and formal charges where necessary. If there is more than one possible structure, draw the structure that minimizes honzero formal charges and fulfills the octet rule.

Lewis structures are used to show the presence of valence electrons and lone pairs on the atoms present in the molecule. It helps to visualise the kind of bonding present between the bonds. N has 5 valence electrons and oxygen has 6 valence electrons. Valence electrons are used for the bond formations in molecules. There can be one or more than one structure for a single compound. These structures are known as resonance structures of each other.
