Based on the conclusions drawn from the gold-foil experiment, Rutherford is also credited with the discovery of the atomic nucleus.byjus.com/chemistry/proton-neutron-discovery/The discovery of the proton is credited to Ernest Rutherford, who first identified the proton in 1917 during his experiment conducted at the University of Manchester. He proved that the nucleus of a hydrogen atom, which is just a proton, is present in the nuclei of all atoms. This means that every atom contains protons in its nucleus.scienly.com/discovery-of-proton/In 1917, Rutherford performed experiments (reported in 1919 and 1925) which proved that the hydrogen nucleus is present in other nuclei, a result usually described as the discovery of protons.en.wikipedia.org/wiki/ProtonErnest Rutherford showed (1919) that nitrogen under alpha-particle bombardment ejects what appear to be hydrogen nuclei. By 1920 he had accepted the hydrogen nucleus as an elementary particle, naming it proton.www.britannica.com/science/proton-subatomic-part…The presence of a positively charged particle in an atom was first observed in 1886 by Eugen Goldstein. It was discovered based on the concept that atoms are electrically neutral. Later in 1917, Ernest Rutherford discovered proton in his famous gold foil experiment.www.sciencefacts.net/proton.htmlProton - Wikipedia
The concept of a hydrogen-like particle as a constituent of other atoms was developed over a long period. As early as 1815, William Prout proposed that all atoms are composed of hydrogen atoms (which he called "protyles"), based on a simplistic interpretation of early values of atomic weights (see Prout's hypothesis), which was disproved when more accurate values were measured.
