Webdistance away from the positive charge in the nucleus. Bohr began with a classical mechanical approach, which assumes that the electron in a one-electron atom is moving in a circular orbit with a radius, r, from the nucleus. The movement of an electron in its orbit would create a centrifugal force, which gives it a tendency to fly away from the ... WebVerified by Toppr. Quantum Condition: The stationary orbits are those in which angular momentum of the electron is an integral multiple of 2πh i.e., L=mvr= 2πnh, n=1,2,3,... Integer n is called the principal quantum number. This equation is called Bohr's quantum condition. Solve any question of Atoms with:-.

WebBohr assumed that the electron orbiting the nucleus would not normally emit any radiation (the stationary state hypothesis), but it would emit or absorb a photon if it moved to a different orbit. The energy absorbed or emitted would reflect differences in the orbital energies according to this equation: Webin the Bohr model. 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)

Web(i) Bohr's Quantization Rule: Of all possible circular orbits allowed by the classical theory, the electrons are permitted to circulate only in those orbits in which the angular momentum of an electron is an integral multiple of 2πh, where h is Plank's constant. Therefore, for any permitted orbit, L=mvr= 2πnh ; n=1,2,3,........ WebThe thing is that here we use the formula for electric potential energy, i.e. the energy associated with charges in a defined system. The Formula for electric potenial = (q) (phi) (r) = (KqQ)/r. We use (KqQ)/r^2 when we calculate force between two charges separated by distance r. This is also known as ESF.
