Question

ANSWER IN DETAIL

Enlist the features of Bohr’s model of an atom. How did he correct the Rutherford’s model ?

Answer 1

Bohr’s Postulates:

1. The extra-nuclear region of an atom consists of electrons revolving in particular orbits called shells.
2. Each shell has a fixed energy level.
3. As long as an electron revolves in the same shell, the energy remains constant. During electronic transition energy is either released or absorbed.
   Bohr corrected Rutherford’s model by suggesting the concepts of energy levels and electronic transition.
