Is it true that $\text{2Pb}{\left({\text{NO}}_{\text{3}}\right)}_2\to 2\text{PbO}+{\text{4NO}}_{\text{2}}+{\text{O}}_{\text{2}}$ it is a fully balanced equation?

A balanced equation contains the same number of atoms of each element in the products side as well as the reactants side.

$\text{2Pb}{\left({\text{NO}}_{\text{3}}\right)}_2\to 2\text{PbO}+{\text{4NO}}_{\text{2}}+{\text{O}}_{\text{2}}$ is a balanced equation.
