Most alpha particles passed through the gold foil undeflected as the nucleus occupies a very small volume compared to the volume of an atom
Rutherford observations - Some
Some alpha particles were deflected through small angles when they passed close to the nucleus showing that charge is concentrated at the centre of the atom, in the nucleus
Rutherford observations - Few
A few alpha particles were deflected through large angles when they passed very close to the nucleus or made a direct collision showing that the mass concentrated at the centre of the atom in the nucleus
