Explain Rutherford’s model of an Atom?
Answers
Explanation:
The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun.
Explanation:
Rutherford conducted experiment with a gold foil bombarded with fast moving alpha particles.
1. A gold foil with 1000 atoms thick has been taken
2. Helium ions are used to bombard the gold foil.
3. It was expected that the alpha particles would be deflected by the subatomic particles in the gold atoms. Since the alpha particles were much heavier than the protons, he did not expected to see large deflections.
Alpha particle scattering experiment output was unexpected
Observations:
a) Most of the fast-moving alpha particles passed through the gold foil
b) Some of the alpha particles were deflected by the foil by small angles.
c) 12000 particles appeared to rebound.
