Obviously, Nitrogen family has 3,5 valencies.But in this case the d-orbital of P interacts with s-orbital of H due to this bond becomes unstable and hence doesn't exists in nature.

In case of P H 5 PH_5 The bond pair electrons of phosphorous and hydrogen come close to phosphorous and thus there is a lot of bond pair repulsion and so it becomes unstable and doesn’t exist while in the case of P F 5 the bond pair of electrons get shifted more towards the fluorine , it being highly electronegative and thus there is separation in bond pair and thus repulsion decreases and it becomes stable \text{The bond pair electrons of phosphorous and hydrogen come close to phosphorous and thus there is a lot of bond pair repulsion and so it becomes unstable and doesn't exist while in the case of } PF_5 \text {the bond pair of electrons get shifted more towards the fluorine , it being highly electronegative and thus there is separation in bond pair and thus repulsion decreases and it becomes stable }
