Question

Explain the observation and conclusion made by user code from the alpha particle scattering experiment

Answer 1

i think it should be Rutherford rather than "user code"

observations:

1. most of the α- particles passed through the gold foil undeflected

2. some of the α-particles were deflected by small angles

3.very few particles deflected back. only one out of 12,000 alpha particles appeared to rebound

Answer 2

The observation made by user code from the alpha particle scattering experiment are:-
1) He saw that many of the alpha particles passes straight away.
2) He saw that some of particles get deflected as they come closer to center.
3) He saw that only a alpha particle from 12000 alpha particles bounce back.

The conclusions are :-
1) The Charge of alpha particles is 4
2) The Center which is nucleus contain a positive charge.
3) He take gold foil because it is the most malleable substance and he required very thin object for this experiment.
