Bohr radius expression
WebFor the Bohr radius rb = h^2 ε0 /π m e^2; take the centrifugal force equals the static electric attractive force in the atom. The ratio of any two of the above numbers is the fine structure constant α=e^2/ε0 hc; and what is notable is that this number is non dimensional, and the three electron radii are obtained in independent processes ... WebInstead of allowing for continuous values for the angular momentum, energy, and orbit radius, Bohr assumed that only discrete values for these could occur (actually, quantizing any one of these would imply that the …

WebAug 18, 2024 · Recently in my class, we used the Bohr model to consider the motion of the nucleus about the center of mass of the electron-nucleus system. I understand that this also happens in the Earth-moon system, where the Earth is kind of wobbling along a point, i.e. the COM is actually inside the surface of the Earth. WebThe Bohr model can be readily extended to hydrogenlike ions, systems in which a single electron orbits a nucleus of arbitrary atomic number Z. Thus Z = 1 for hydrogen, Z = 2 for He+, Z = 3 for Li++, and so on. The Coulomb potential (5) generalizes to V(r) = ¡ Ze2 r; (18) the radius of the orbit (13) becomes r n = n2a 0 Z (19) and the energy ...
