Comparing Orbitals of H and He+

  1. Dec 13, 2011 #1
    1. The problem statement, all variables and given/known data
    Both H and He+ atoms contain a nucleus and a single electron. Therefore He+ is often referred to as Hydrogen-like. According to the Bohr Model, the electron in He+ should orbit the nucleus in discrete orbits, much like the electron in the Hydrogen atom orbits its nucleus. How will the electron's orbital of He+ differ from the elctron's orbits of a H atom?


    2. Relevant equations



    3. The attempt at a solution I don't see how their orbits will be different because they are both found within a 1s orbital which are spherical. Would they have different levels of energy? If so how could you go about figuring this?

    I'm not sure about calculating energy levels, but if you consider the amount of protons in a He+ atom versus a H atom, there are twice as many. This extra positive charge should cause a greater attraction inward on the proton. I think this change will also change the energy levels but can't help you with the calculations.
