Homework Help: Uncertainty principle and hydrogen atom electron

  1. Feb 23, 2009 #1
    1. The problem statement, all variables and given/known data

    Using the uncertainty principle find the energy required for the electron to be confined inside the hydrogen atom. Use the radius of the atom 1 x 10-10 m for Δr. Express your answer in eV, rounded up to the nearest hundredth.

    2. Relevant equations

    x=position in space
    3. The attempt at a solution

    is is the radius of the atom=Δx? and if it is how do i get the momentum of the electron?
