How did ernest rutherford discover protons
WebBetween 1908 and 1913, Rutherford, Geiger, and Marsden ran a series of experiments where they pointed a beam of alpha particles at a thin foil of metal and, [7] using the scintillation method devised by Crookes, Elster, and Geitel, [8] [9] studied the scattering pattern of the alpha particles with the aid of a fluorescent screen. WebThese protons add the overall positive charge of a molecule. The mass of the proton is 1.6727g x 10 raised to -24, the electron 9.110g x 10 raised to -28. Through scientific discovery, protons have been accepted as the particle that contributes to the positive charge of an atom. The discovery of protons can be attributed to Rutherford.
