Question

explain, how was proton discovered​

Answer 1

Answer:

In 1909, Rutherford discovered proton in his famous gold foil experiment. He bombarded alpha particles on an ultrathin gold foil. ... Based on Wilhelm Wien's theory, who in 1898 discovered the proton in streams of ionized gas, Rutherford postulated the hydrogen nucleus to be a new particle in 1920, which he called proton.

Answer 2

Who Discovered Proton?

The three different sub-atomic particles of an atom namely, protons, were discovered in the nineteenth and twentieth century. neutrons and electrons

Discovery of Protons

The presence of positively charged particle in an atom had been first observed in 1886 by E. Goldstein based on the concept that atoms are electrically neutral i.e., it has same number of positive and negative charge. He performed a series of experiments and observed that when a high voltage electricity passed through a cathode tube fitted with a perforated cathode (pierced disk) containing gas at low pressure a new type of ray was produced from positive electrode (anode) which moves towards cathode. These new rays he termed as canal rays, positive rays, or anode rays.

In 1909, Rutherford discovered proton in his famous gold foil experiment. He bombarded alpha particles on an ultrathin gold foil. Rutherford thought that a hydrogen nucleus must be fundamental building block of all nuclei, and also possibly a new fundamental particle as well, since nothing was known from the nucleus that was lighter. Based on Wilhelm Wien's theory, who in 1898 discovered the proton in streams of ionized gas, Rutherford postulated the hydrogen nucleus to be a new particle in 1920, which he called proton. Rutherford named it the proton, from the Greek word "protos," meaning "first."
