NF3 is possible but NF5 is not why?

The electronic configuration
Of N= 1s2 2s2 2p3
N has 3 electrons in its valence shell so it can form compound NF3
But as N doesnt have any d orbital so it cannot expand its octet due to which N cannot form NCl5 compound.

The valency of nitrogen is 3.
It has 5 electrons in its outer most orbit,but take a look at the electronic configuration .
N - 1s2, 2s2, 2p3
It has 3 electrons in 2p orbital. Since there is no vacant 2d orbital (which is also not possible,it does not exist) to complete it's octet , that means to expand so N can only form NF3 not NF5.
