How did ernest rutherford discover protons
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. 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.
