Question

explain the rutherford's model of an atom
is it right or not please answer

Answer 1

$\mathbb{\huge{\bold{\red{Hello}}}}$
$\underline\bold{Your\: answer}$

His model.. he selected a gold foil because he wanted as thin layer as possible this gold foil was about 1000 atom thick.
a particles are double charged helium ions since they have a mass of 4u The fast moving a-particles have a considerable amount of energy.


It was expected that a-particles would be deflected by the sub-atomic particles were much heavier than the protons .

OBSERVATION..
The following observations are..


Most of the fast moving a particles passed straight thought gold foil.


some of the a particles were deflected by the foil by small angles.


Surprisingly one out of every 12000 particles appeared to rebound..
