The Bohr model of the atom was proposed by Neil Bohr in 1915. It came into existence with the modification of Rutherford’s model of an atom. Rutherford’s model introduced the nuclear model of an atom, in which he explained that a nucleus (positively charged) is surrounded by negatively charged electrons. See more Bohr theory modified the atomic structure model by explaining that electrons move in fixed orbitals (shells) and not anywhere in between and he also … See more Bohr’s theory is applicable to hydrogen-like species containing one electron only e.g. Li2+. Bohr’s theory is applicable to hydrogen like atoms (single electron system). Li2+ and H-atom consists of only one electron.

WebOct 2, 2024 · What are Bohr’s postulates Class 12? October 2, 2024 by George Jackson. Postulates of Bohr’s Model of an Atom In an atom, electrons (negatively charged) revolve around the positively charged nucleus in a definite circular path called orbits or shells. Each orbit or shell has a fixed energy and these circular orbits are known as orbital shells. WebThe value of Bohr’s radius is 0.529×10-10m. The energy calculation of an electron at the nth level of hydrogen is formed by considering the electrons in circular orbits. The equation is as follows: E (n)= 1/n2 × 13.6eV.
