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 WebbBohr postulated that electrons orbit the nucleus in discrete energy levels, and electrons can gain and lose energy by jumping between energy levels, giving off radiation of frequency ν according to the formula Δ E = E 2 − E 1 = h ν where ν = 1 T, where T is the period of orbit, as in classical mechanics. coreboard wood https://barmaniaeventos.com
