WebJul 16, 2024 · Bohr described the hydrogen atom in terms of an electron moving in a circular orbit about a nucleus. He postulated that the electron was restricted to certain orbits characterized by discrete energies. Transitions between these allowed orbits result in the absorption or emission of photons.

"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. For a hydrogen atom, the classical orbits have a period T determined by Kepler's third law to scale as r3/2. " - In bohrs stationary orbit

WebApr 5, 2024 · Bohr's model is based on the following postulates: → He postulated that an electron in an atom can move around the nucleus in certain circular stable orbits without emitting radiations. → Bohr found that the magnitude of the electron's angular momentum is quantized i.e. L = mv n r n = n (h/2 π) 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:-.

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.
