1 janv. 1911 - Ernest Rutherford
Description:
Rutherford fired positively charged alpha particles at a thin sheet of gold foil. Most passed through with little deflection, but some deflected at large angles. This was only possible if the atom was mostly empty space, with the positive charge concentrated in the centre, the nucleus.Ajouté au bande de temps:
