What are the postulates of Bohr’s model of an atom?

WebBohr’s model of the hydrogen atom was no doubt an improvement over Rutherford’s nuclear model, as it could account for the stability and line spectra of a hydrogen atom and hydrogen-like ions (for example He +, Li 2+, Be 3+ and so on). Merits of Bohr’s theory: (i) The experimental value of radii and energies in a hydrogen atom are in good agreement … WebJan 25, 2024 · According to Bohr’s calculation, for the hydrogen atom, the energy for an electron in the specific orbit is given by the expression: \ (E (n) = -\frac {13.6\,\rm {eV}} {n^2}\) The hydrogen spectrum can be explained in terms of electrons absorbing and emitting photons to change energy levels, where the photon energy is:

WebModule 1 Test Remediation page 2 11. The electron orbits in Bohr’s atomic model predict exactly where an electron is located. What do Bohr’s orbits look like? (1.11.1) looks like the Sun with the electrons revolving around it like planets in their orbits. 12. Electron orbitals (in the Quantum Mechanical model of the atom) do NOT predict exactly where an electron … WebJan 27, 2024 · The simplest example of the Bohr Model is for the hydrogen atom (Z = 1) or for a hydrogen-like ion (Z > 1), in which a negatively charged electron orbits a small positively charged nucleus. Electromagnetic energy will be absorbed or emitted if an electron moves from one orbit to another. Only certain electron orbits are permitted.

WebPostulate III According to this postulate, an electron can transition from a non-radiating orbit to another of a lower energy level. In doing so, a photon is emitted whose energy is equal to the energy difference between the two states. According to Bohr's postulates, For a dynamically stable orbit in a hydrogen atom, Also, Equating (1) and (2), b)

WebThis expression is commonly known as Bohr’s frequency rule. The angular momentum of an electron in a given stationary state can be expressed as mvr = n h π n × h 2 π. where, n = 1, 2, 3. Thus, an electron can move only in those orbits for which its angular momentum is an integral multiple of h/2π.
