Question

what is Rutherford's model of an atom ?​

Answer 1

Answer:

he said that the atom revolves around the shells of it and by revolving the atom loses its energy and fall into nucleus

he did not able to explain its stability

RUTHERFORD ATOMIC MODEL OR ALPHA SCATTERING EXPERIMENT

• α−ray is the flow of the 2+ ions
• Alpha ray is bombarded over thin gold foil.

OBSERVATION

• Most of the Alpha particle pàss through the thin gold foil without any deflection.
• Sum of Alpha particle get deflected through less than 90°
• Very few of Alpha Ray pàss through thin gold file with deflection angle more than 90°
• One ray in 15000 rays shows deflection through 180°.

CONCLUSION OF RUTHERFORD MODEL

• Most part of the atom are empty.
• Centre of the atom have highly dense reason which is positively charged reason known as nucleus.
• Total mass of atom is concentrated in nucleus.
• Size of nucleus is very less as compared to size of the atom.
• Volume of atom = 10¹⁵ × Volume Of Nucleous
• Electron revolves around the nucleus in circular path.
