WebJun 6, 2024 · The Bohr's postulates - 1) An electron can revolve around the nucleus in certain fixed orbits of definite energy without emission of any radiant energy. Such orbits are called stationary orbits.
WebPostulates of Bohrs Atomic Model Distribution of Electrons in Orbits In 1915, Niels Bohr proposed Bohr’s Atomic Model. This model was a modification of Rutherford’s atomic model. Bohr’s model of an atom is also known as the Rutherford-Bohr Model.
WebThe postulates of Bohr’s Model of Hydrogen Atoms are given by:- The electrons of the hydrogen atom revolve around in stable orbits without emitting any radiant energy. In the stationary orbit of the atom, the angular momentum is the multiple of the equation h/2π and L=nh/2π , where n is called the quantum number. sbi life insurance for nrisWeb12.
