Diameter of a ground-state hydrogen atom
WebAug 10, 2015 · $\begingroup$ I think at this level the problem just wants you to equate the energy of the hydrogen ground state to the energy of an electron in its ground state in a finite square well and solve for L. I don't think you are actually supposed to derive the hydrogen atom ground state energy. WebMay 9, 2014 · For this model recall that the electron orbitsheld in place by a coulomb like force. m e v 2 r = 4 π ϵ 0 e 2 r 2. Now the total energy is given by the (coloumb like) potential and kinetic energy. E = U + K. Use the first equation to get rid of the v terms and solve for the ground state. See wikipedia for more details.

WebSuppose an empty universe with the exception of a single hydrogen atom (1 proton, 1 electron). The electron may be in its ground state or it may be excited a certain number … WebAug 28, 2024 · However, no atom other than hydrogen has a simple relation analogous to Equation 1.7.1 for its spectral frequencies. Bohr in 1913 proposed that all atomic spectral lines arise from transitions between discrete energy levels, giving a photon such that. ΔE = hν = hc λ. This is called the Bohr frequency condition.
WebDec 19, 2024 · That said, however, the Bohr radius a_0 = 5.29*10^-11m is the distance between the nucleus and the most probable position of the electron. Doubling this distance gives the diameter, not from the “edge” of the atom to the opposite edge, but the diameter that the electron is most likely to be found orbiting at. So 1.58*10^-10m. WebSep 11, 2015 · The uncertainty in the momentum of an electron in an atom is defined as: ( Δ P) 2 = P 2 − P 2. An electron bounded by the nucleus, has an average momentum of zero, which means ( Δ P) 2 = P 2 , but again, Feynman's explain, as explained in the comment, was a really hand-wavy approach towards approximating the size of an atom.
