"WebThe Bohr model of the atom was proposed by Neil Bohr in 1915. It came into existence with the modification of Rutherford’s model of an atom. Rutherford’s model introduced the nuclear model of an atom, in which he explained that a nucleus (positively charged) is surrounded by negatively charged electrons. " - In bohrs stationary orbit

WebAn object moving in a circular orbit lost energy but according to Bohr electrons in orbitals do not lose energy. if they lose energy then they fall into the nucleus and hence atom will … WebBohr's model of atoms: the tiny nucleus with electrons revolving in the concentric orbits. The electrons are bounded to the nucleus by the electrostatic force between them. Unlike the earlier Rutherford model, the orbiting electrons do not continuously radiate energy. The orbits, aka stationary orbits, are stable and discrete with a fixed radius.

The stationary orbits of Bohr were understood as orbits whose length had integer number of de Broglie wavelengths. 5 Spin In 1922 Sterl & Gerlach reported experiments which led to the conclusion that electron (in this case the valence electron of Silver) had a spin of s= 1=2hand an associated magnetic moment s = g s Bs (11)

WebBohr considered circular orbits. Classically, these orbits must decay to smaller circles when photons are emitted. The level spacing between circular orbits can be calculated with the correspondence formula.
