Bohr’s Model of Atom 1- Electrons revolves around the nucleus in definite energy levels called orbits or shells in an atom without radiating energy. 2- As long as an electron remain in a shell it never gains or losses energy. + - - - n = 3 n = 2 n = 1 Prepared by: Sidra Javed. Web5 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
