Answer 2

Rutherford's Model of an Atom:

• Rutherford's model is also known as Nuclear atomic model.

• Rutherford stated that an Atom consists of a heavy positively charged nucleus where all the protons and neutrons are present

• Almost whole of the mass is contributed by protons and neutrons.

• The volume of the nucleus is very small and is a minute fraction of total volume of Atom.

• There's an empty space around the nucleus which is called extra nuclear space.

• Electrons revolve around the nucleus in closed orbits with high speed.

Drawbacks:

• This model couldn't explain the stability of Atom.

• According to Maxwell, electron loses its energy continuously in the form of electromagnetic radiation. As a result e- should be losing energy while revolving around the nucleus. In this way the electron will ultimately fall in the nucleus.

• If electron looses energy continuously then it would produce a continuous spectrum. But the actual electron spectrum has well defined lines of definite frequencies.
