an atom consists a positively charged , dense nucleus called nucleus.
the electron move around the nucleus in a circular path within discrete orbits.
an atom is an empty space.
Rutherfords experiment on scattering of partical showed for the first time that the atom has nucleus.
Ernst Rutherford alpha particle scattering experiment is the most famous and milestone of atomic physics. he observed during this experiment :
1. A major part of alpha particles penetrate gold foil .it means , most of the space of atom is empty.
2. some of alpha particles deflect from its path. it means,
2. some of alpha particles were deflected by the gold foil by very small angles . it means, distribution of positive particles of an atom is non uniform.
3. very few of alpha particle deflected back. it means,volume occupied by the positively charged particles in an atom is very small as compared to the total volume of an atom.
from above observations Rutherford sir proposed the atomic structure of element and he said “The positively charged particles and most of the mass of an atom was concentrated in an extremely small volume. this region of the atom is a nucleus”
