Question

Bohr's atomic model​

Answer 1

In 1913, Niels Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities. Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted.

Answer 2

• he made following assumptions:
• 1) stability of atom= electrons do not loose energy while revolving around nucleus so electrons do not collide in nucleus.
• 2) certain number of electrons revolve in particular orbit.
• 3) no. of electrons present in orbit=2nsquare.
