NettetSolution. Verified by Toppr. Three postulates of Bohr are. 1. An atom has a number of stable orbits in which an electron can reside without the emission of radiant energy. Each orbit corresponds, to a certain energy level. 2. An electron may jump spontaneously from one orbit (energy level E 1) to the other orbit (energy level E 2) ( E 2>E 1 ...

NettetThe Limitations of Bohr's model are, 1) The Bohr atomic model theory made correct predictions for smaller sized atoms like hydrogen, but poor spectral predictions are obtained when larger atoms are considered. 2) It failed to explain the Zeeman effect when the spectral line is split into several components in the presence of a magnetic field. NettetLimitation of Bohr's Theory . 1) According to Bohr, the radiation results when an electron jumps from one energy orbit to another energy orbit, but how this radiation occurs is not explained by Bohr. 2) Bohr Theory had explained the existence of various lines in H-spectrum, but it predicted that only a series of lines exist.

NettetBohr’s model for hydrogen atoms could not explain the line spectra of atoms other than hydrogen. Even for hydrogen, a more accurate study of the observed spectra showed multiple components in some lines which could not be explained on the basis of this model.

Nettet21. sep. 2015 · Bohr’s theory was unable to explain the following observations; (i). Bohr’s Model could not explain the spectra of atoms containing more than one electron. (ii). It could not explain the Zeeman effect. In presence of magnetic field, each spectral line gets split up into fine lines, the phenomenon, is known as Zeeman effect. NettetLimitations of Rutherford's model of the atom: His model failed to explain the stability of atoms. The arrangement of electrons in a circular path was not defined. Any particle that is moving in a circular path would undergo acceleration and radiates energy. Thus, the revolving electron would lose energy and finally fall into the nucleus.

NettetModern atomic theory, or more specifically quantum theory, describes an electron as not occupying a circular orbit at a fixed distance from the nucleus, unlike in the Bohr model. Instead, the electron can occupy a range of different positions, although with differing probabilities. We can think of the electron being a set distance from the ...

NettetLimitations. According to Danish physicist Niel Bohr’s atomic model, an atom includes a small, charged nucleus surrounded by electrons that journeys in round orbits across the nucleus with force supplied through electrostatic forces. This version of Bohr’s theory was entirely based on Planck’s quantum principle of radiation.
