Expert Answer

Step 1

Bohr’s theory of atoms was applicable for one electron system. It purposed the energy levels in an atom. These energy levels are occupied by electrons. Electrons can show the transition between these energy levels that involves certain energy. The excitation requires energy whereas, transition from the higher level to lower level release a certain amount of energy.

 

Step 2

Bohr’s theory of atoms was applicable to the one electron system. It purposed the energy levels in an atom. It purposed the mathematical relation for the calculation of the radius of orbits, energy and velocity of electrons.
