Models of an Atom: Limitations of Bohr’s Model

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.

Nettet6. apr. 2024 · Postulates of Bohr’s model of an Atom. 1) An atom consists of a small, heavy positively charged nucleus in the centre and electrons revolve around it in circular orbit. 2) The electrons revolve only in those orbits which have a fixed value of energy. These orbits are called energy levels or stationary States. NettetTriumphs and Limits of the Bohr Theory. Bohr did what no one had been able to do before. Not only did he explain the spectrum of hydrogen, he correctly calculated the size of the atom from basic physics. Some of his ideas are broadly applicable. Electron orbital energies are quantized in all atoms and molecules. Angular momentum is quantized.
