- Proton was discovered by Ernest Rutherford in 1909 through his famous gold foil experiment123. In this experiment, Rutherford bombarded alpha particles on an ultrathin gold foil and then detected the scattered alpha particles on zinc sulphide (ZnS) screen1. Rutherford proved that the nucleus of the hydrogen atom (i.e. a proton) is present in the nuclei of all other atoms in the year 19173. Based on the conclusions drawn from the gold-foil experiment, Rutherford is also credited with the discovery of the atomic nucleus3.
