Document Summary
, where z is the is the principal quantum number, and hr is the rydberg constant for the. 1410, 11/07: note the general formula for hydrogenic atom energy levels: atomic number, hydrogen atom: numerically, i)(8 points) ignoring the other electron , the tagged electron feels the bare (unscreened) z=+2 helium nucleus. [note: the experimentally measured first ionization potential for ground state he is ~25ev. ] in the range 13. 6 ev e. 1 bind (c) (8 points)from ps7, we know that for a hydrogenic atom in an l=0 state, 0a is the hydrogen atom bohr radius; numerically, a = r n. 2 have the same meaning as above, and. Following the reasoning above, in the extreme case that the tagged electron does not feel the other electron"s presence at all (because the tagged electron lies inside the other electron at all times), then the effective. 0. 53 value of z is 2, and r< > =
