Homework Help: Electron in infinite well equation

  1. May 16, 2012 #1
    1. The problem statement, all variables and given/known data

    An electron is confined in an infinitely deep well of width 0.1nm, about the size of an atom. Estimate the energy of the ground state in eV.

    2. Relevant equations

    Is this the equation I should be using?

    E=(n^2 hbar^2 ∏^2)/(2m L^2)

    3. The attempt at a solution

    Yes, assuming you're using 1-dimension. (The way the problem statement was worded, it sounds to me like 1-dimentional quantum mechanics is a reasonable assumption.)
