Such orbits …
WebbWhat are the postulates of Bohr’s model of an atom? Solution: The main postulates of the theory are listed: 1. In the extra nuclear portion of an atom, the electrons revolve in well defined circular paths known as orbits. 2. These circular orbits are also known as energy levels or energy shells. 3. Webb31 jan. 2024 · According to the Rutherford’s model of an atom, a nucleus (positively charged) is surrounded by negatively charged electrons. Bohr modified this atomic …

WebbSince Bohr’s model involved only a single electron, it could also be applied to the single electron ions He +, Li 2+, Be 3+, and so forth, which differ from hydrogen only in their nuclear charges, and so one-electron atoms and ions are collectively referred to as hydrogen-like atoms.
Webb5 apr. 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. Angular Momentum (L) = mvr = n h 2 π egライフ 解約方法WebbBohr's atomic model. 5 mins.
