Web17 de ago. de 2024 · Discovery of Protons The nucleus of the atom was discovered by a scientist named Ernest Rutherford in the year 1911 in his well-known gold foil experiment. He stated that all the positively charged particles present in an atom were concentrated in a singular core and that maximum of the atom’s volume was empty. WebThe next step in the journey—the discovery of atomic nuclei consisting of protons and neutrons—was made by the New Zealand-born British scientist Ernest Rutherford, and his students. Rutherford’s experimental work was designed to identify the nature of radioactivity, which Marie Curie had discovered in 1897.

He called these particles protons and realized that they were a fundamental particle in the nucleus. Protons have a mass of 1.673 x 10-24 grams, about 1,835 times larger than an electron! 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.
