Important points of Bohr’s model of the atom are following:
- Atom has nucleus in the centre.
- Electrons revolve around the nucleus.
- Certain special orbits known as discrete orbits of electrons are allowed inside the atom.
- While revolving in discrete orbits the electrons do not radiate energy.
- These orbits or shells are called energy levels.
- These orbits or shells are represented by the letters K, L, M, N or the numbers n = 1, 2, 3, 4.
