mention the short comings of Ruther ford's model of en atom?​

Answer 1

• Rutherford’s model was unable to explain the stability of an atom. According to Rutherford’s postulate, electrons revolve at a very high speed around a nucleus of an atom in a fixed orbit. However, Maxwell explained accelerated charged particles release . Therefore, electrons revolving around the nucleus will release electromagnetic radiation.
• The electromagnetic radiation will have energy from the electronic motion as a result of which the orbits will gradually shrink. Finally, the orbits will shrink and collapse in the nucleus of an atom. According to the calculations, if Maxwell’s explanation is followed Rutherford’s model will collapse with 10-8seconds. Therefore, Rutherford atomic model was not following Maxwell’s theory and it was unable to explain an atom’s stability.
• Rutherford’s theory was incomplete because it did not mention anything about the arrangement of electrons in the orbit. This was one of the major drawbacks of Rutherford atomic model.

Answer 2

Answer:

RUTHERFORD'S ATOMIC MODEL:

☆The atom contains large space.

☆There is a positively charged mass ate the atom,know as nucles.

☆The size of the nucleus of an atom is very small compared to the size of an atom.

☆The electrons revolve around the nucleus in close circular path.

☆An atom as a Whole is electrically neutral,I.e.,the number of protons and electrons in an atom are equal.
