Question

×_× DESCRIBE Rutherford Model Of Atom ×_×​

Answer 1

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.

RUTHERFORD ATOMIC MODEL

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

CONCLUSIONS

• As most of the alpha-particles passed through foil undeflected, it means most of the space of the gold atom is empty.
• A few positively alpha-particles were deflected because of a very small nuclear position of the gold atoms.
• By this Rutherford conclude that the volume occupied by the nucleus is very small as compared to the nucleus of an atom.
