Question

describe the model of the atom suggested by Rutherford. what was the drawback of this model? what was Niels Bohr's contribution to finding out the structure of the atom?

Answer 1

Dear student,

Main features of Rutherford Model is-

• There is dense position at the centre of nucleus which is called nucleus.
• Electrons move around nucleus.
• Most of the space in atom is empty.

According to Rutherford model, electrons move around nucleus. But such moving particles get acceleration and these accelerated particles radiate energy and fall into the nucleus. This will make the total system unstable. This is the major drawback of Rutherford model.

Niels Bohr's theory depends on quantum model. He proposed that electrons move around the nucleus only in particular orbit of a constant energy. If electrons jump from higher energy to lower energy orbital, a quanta of light is emitted.
