(I) S.W.E cannot be exactly solved for multi electron species.

With the increase in nuclear charge, orbitals get contracted.

Moreover in such species the energy of orbitals depends not only on principal quantum number but also on azimuthal quantum number. 

(II) ….incorrect ;

In hydrogen atom, energy of 1s<2s=2p<3s=3p=3d<4s=4p=4d=4f
