Question

Write any three features of Rutherford 's atomic model.

Answer 1

The positively charged particles and most of the mass of an atom was concentrated in an extremely small volume. He called this region of the atom as a nucleus.

Rutherford model proposed that the negatively charged electrons surround the nucleus of an atom. He also claimed that the electrons surrounding the nucleus revolve around it with very high speed in circular paths. He named these circular paths as orbits.

Electrons being negatively charged and nucleus being a densely concentrated mass of positively charged particles are held together by a strong electrostatic force of attraction.

Answer 2

Hi ,

here is your answer:

i) There is a positively charged centre in an atom called the nucleus. Nearly, all the mass of an atom resides in the nucleus.

ii) The size of the nucleus i.e., 10-15m is very small compared to the size of the atom (i.e., 10-10 m).

iii) The electrons rotate around the nucleus in well-defined orbits.

Hope u like my answer!!
