1. The problem statement, all variables and given/known data Please see the attachment for a better picture The energy of an electron in a hydrogen atom is: E = p^2/2m - αe2/r; where p is the momentum, r the orbital radius, me the electron mass, e the electron charge, and α the Coulomb constant. Use the uncertainty principle for momentum vs. position to estimate the minimum radius and the momentum corresponding to this radius. 2. Relevant equations E = p^2/2m - αe2/r I'm not exactly sure what this means conceptually 3. The attempt at a solution Is this a plug and chug? I feel like it's not that simple. uncertainty for momentum says delta x * delta p <= h/2π so do I just plug in p in delta p?
