Question

Describe the Rutherford's effort a ray scattering experiment and mention the observation derived from it cite one defect of the Rutherford model of the atom

Answer 1

Answer:

RUTHERFORD SCATTERING EFFECT

OBSERVATION

• Maximum alpha - particles passes through the gold foil without any deflection that means maximum part of atom is empty.
• Some alpha - particles are deflected from their path that means the total positive charge of atom is centralised and this point is called as nucleus.
• Very few alpha - particles (1 out of 20,000) come out with 180° that means size of nucleus is very small as compared to atom.

DEFECT

• According to Maxwell when electron revolve around the nucleus. Then, it should losses it's energy and fall down on the nucleus.
• The spectrum of atom should be continuous but spectrum of atom is found line spectrum.

Answer 2

Answer:

Maximum alpha - particles passes through the gold foil without any deflection that means maximum part of atom is empty. Some alpha - particles are deflected from their path that means the total positive charge of atom is centralised and this point is called as nucleus
