Question

describe the rutherford's model of an atom state one drawback of Rutherford Model of the atom

Answer 1

1. an atom has a dense,heavy,positively charged central part of called nucleus
2. the total electrons are present at very large distances from the nucleus
3.the total positive charge on the nucleus is equal to the total negative charge on all the electrons so that atom on the whole is ellectrically neutral
4.the electrons are revolving around the neuclous so that attractive force of the nucleus is balanced by the centrifugal force



drawback
1. it could not explain the stability of an atom when charged electrons are moving under the attractive force of positively charged nucleus........... hope it will help u

Answer 2

Points on Rutherford's model are:-

1. An atom consists of two particles that is the nucleus and extra nuclear portions.

2. The nucleus is present at the centre of the atom.

3. The positive charge is due to the presence of protons. Since the atoms differ in the number of protons Therefore, the magnitude of the positive charge on the nucleus differs from atom to atom.

4. Extranuclear portion was referred to as the space around the nucleus where the electrons are present.

5. Total positive charge on the nucleus is equal to the total negative charge on the electrons and the atom as a whole is electrically neutral.

6. The electrons present in the extranuclear space are revolving around the nucleus at a high speed in circular orbits.

Drawbacks of Rutherford's model are as follows :-

1. Stability of atoms was not explained.

2. Only some waves appeared on spectrum.

3. Electrons will collide with nucleus as stated according to the maxwell theory.
