1. Mainly for hydrogen 2. Could not explain the spectra of multi electron atoms 3. In bohr model, an electron is regarded as a charged particle moving in a well defined circular orbit about the nucleus. The wave character of the electron is ignored in bohr theory. And doesn't follow de broglie's concept of wave particle duality for matter

When the electron gains energy it moves to a higher energy level, then drops back to the ground state releasing its excess energy as light.The upper animation shows how blue (higher energy) light and the animation to the left shows how red (lower energy)light is created.

A cyclotron is a device which is used to accelerate charged particles to higher energies.

PRINCIPLE: when a charge q moves normal to a magentic field it experiences magnetic lorentz force due to which it moves in circular path .

when a charged particle of mass ' m' and charge q is accelerated towards the Dee having -ve polarity at that instant and normal magnetic field produces magnetic lorentz force which provides centripetal force for the electron to move in a circular path of radius 'r' .By the time the particle reaches the gap the polarity changes thus the particle is again accelerated towards the Dee having -ve polarity at that instant. thus the particle moves in spiral path increasing the radius and velocity.we it reaches the edge the particle is taken out with the help of a deflector plate

Binding energy, amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system. ... In general, the binding energy of a single proton or neutron in a nucleus is approximately a million times greater than the binding energy of a single electron in an atom
