The angular shape of the ozone molecule (${\text{O}}_3$) consists of:

Shutterstock Explore The structure of Ozone (${\text{O}}_3$) can be represented as a resonance hybrid of two main structures. In either structure:The central oxygen atom is bonded to one terminal oxygen atom by a single bond (which is $1$ sigma bond).The central oxygen atom is bonded to the other terminal oxygen atom by a double bond (which consists of $1$ sigma and $1$ pi bond).Total count:Sigma ($\sigma$) bonds = $1+1=2$ Pi ($\pi$) bonds = $1$ Thus, the molecule consists of $2$ sigma and $1$ pi bond.
