Statement I: Lithium needs less energy to knock off an electron from its outermost orbit than Helium. Statement II: Lithium has 1 electron in its outermost orbit which is loosely bonded to the nucleus, due to the repulsion of the electrons present in the inner orbit and located at a greater distance from the nucleus.
