From His Experiments, How Did Rutherford Conclude That Most of The Space Inside An Atom Is Empty?



 Physicist Ernest Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections. Every atom has a nucleus where all of its positive charge and most of its mass is concentrated.

He concluded that most (99%) of all the mass of an atom is in the nucleus of the atom, that the nucleus is very small (1000th of the size of an atom) and that is positively charged. Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus.
