Question

What is Rutherford's model of an atom?​

Answer 1

Answer:

The Rutherford model was devised by Ernest Rutherford to describe an atom. Rutherford directed the Geiger–Marsden experiment in 1909 which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect. Rutherford's new model[1] for the atom, based on the experimental results, contained new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume also containing the bulk of the atomic mass of the atom. This region would be known as the "nucleus" of the atom.

RUTHERFORD ATOMIC MODEL

• 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.
