Question

What are the postulates of Bohr’s model of an atom?

Answer 1

According to Neils Bohr’s model of the structure of the atom

1. Electrons revolve around the nucleus in fixed paths called orbits.
2. Only certain special orbits are allowed inside the atom.
3. While revolving in discrete orbits the electrons do not radiate energy. They absorb energy to go to the higher level and emit energy to go to the lower level. These orbits are called energy levels which are represented as K, L, M, N or 1, 2, 3, 4
