Covalency of N is 4 in \mathrm{N_{2}O_{5}}, and its oxidation state is +5.

As clear from the structure of \mathrm{N_{2}O_{5}}, covalency of nitrogen is 4 but the oxidation state is +5.

\mathrm{N_{2}O_{5}} is a neutral compound. Let the oxidation state of \mathrm{N_{2}O_{5}}  be x.

\begin{aligned} & \mathrm{(2 \times x)+(-2 \times 5)=0} \\ & \mathrm{2 x-10=10} \\ & \textup{x = 5} \end{aligned}
