SUMMARY
The binding energy of the 2p electron in Lithium is closely related to the n=2 state of Hydrogen due to similar principal quantum numbers and effective nuclear charge. The 2p state (n=2, l=1) experiences less shielding from the inner electrons compared to the 2s state (n=2, l=0), resulting in a higher energy level for the 2s state, which is approximately 5.4 eV. This difference arises from the angular momentum of the 2p electron, allowing it to be less influenced by the other electrons in the atom.
