Question

write any two conclusions of Rutherford a- particle scattering

Answer 1

${\pink{\mathbb{Hola!!}}}$

Rutherford observed that
1) most of the a-particles passed straight through the gold foil.
2)some we're deflected by small angles.
3)one out of every 12000 particles appeared to rebound.

indicating that:-

1)most space inside atom is empty
2) positive charge occupies very little space.
3)all mass of an atom resides in nucleus and nucleus is concentrated with positive charged centre.
