WebBohr Model r 2 m v 2 = r 2 K e 2 m v r r = n 2 π h (2) In the Bohr model of the hydrogen atom (1910), the electron is assumed to move around a circle with radius r. Tire model is based on two equations: (i) Newton's 2nd law for circular motion, and (ii) Bohr's hypothesis of quantized angular momentum. (A) For quantum number n = 3, what is the ... WebBohr sought to avoid an atomic catastrophe by proposing that certain orbits of the electron around the nucleus could be exempted from classical electrodynamics and remain stable. The Bohr model was quantitatively successful for the hydrogen atom, as we shall now show. We recall that the attraction between two opposite charges, such as
