How is Hamiltonian energy of orbital differ from orbital in certain

[boodyx1]

how is Hamiltonian energy of orbital differ from orbital in certain atom with another atom although the two orbital have the same no. of electrons...
ex...Hamiltonian energy differ in lithium and hydrogen although both have one electron in last orbital
please help me quickly

lol, just curious, why the rush? ;]

Well these 2 atoms you mention have nothing in common. They have different atomic number, which means the potential V (that gets in Schrödinger equation) is different which finally means that you'll get different Hamiltonian eigenstates (energies)

r u trust in this answer...and how the atomic no. can change in V
