In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.
Bohr’s model of atom can be defined as, electrons orbits in the nucleus at set distances. When an electron jumps from one orbit to another, it does so with a sudden quantum leap. The energy difference between the initial and final orbit is emitted by the atom as a bundles of electromagnetic radiation called photons.
Main points of Bohr’s model of atom are as follows:
1) Electrons revolve around nucleus in orbits which have a set size and energy.
2) The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.
3) Radiation is absorbed or emitted when an electron jumps from one orbit to another.
