Question

state any four observation made by Rutherford​

Answer 1

Answer:

There were only 3 observations..

Explanation:

1. Most of the alpha particles passed through the foil..
2. Some alpha particles deflected from their path..
3. Surprisingly, 1 out of 12000 particles hit an angle of 180 degrees.

Answer 2

Explanation:

1.major fraction of the α-particles bombarded towards the gold sheet passed through it without any deflection, and hence most of the space in an atom is empty.

2.Some of the α-particles were deflected by the gold sheet by very small angles, and hence the positive charge in an atom is not uniformly distributed. The positive charge in an atom is concentrated in a very small volume.

3.Very few of the α-particles were deflected back, that is only a few α-particles had nearly 180o angle of deflection. So the volume occupied by the positively charged particles in an atom is very small as compared to the total volume of an atom.

Rutherford Atomic Model

Based on the above observations and conclusions, Rutherford proposed the atomic structure of elements.
