-
Most of the particles passed either undeviated or with very small deviation.
-
Some deviated by large angles
-
1 out of 8000 was deflected by more than 90°
-
Most of the space of an atom is empty.
-
At the centre of an atom having a tiny positively charged particle called a nucleus.

The centre nucleus has all the mass of an atom.
-
The amount of positive charge at the nucleus is equal to the total amount of negative charge on all the electrons of the atom.
