How did Rutherford eject a proton?
How did Rutherford discover alpha particles?
Rutherford's discoveries include the concept of radioactive half-life, the radioactive element radon, and the differentiation and naming of alpha and beta radiation. Together with Thomas Royds, Rutherford is credited with proving that alpha radiation is composed of helium nuclei.
The nucleus of the atom was discovered by Ernest Rutherford in the year 1911 in his famous gold foil experiment. He concluded that all the positively charged particles in an atom were concentrated in a singular core and that most of the atom’s volume was empty.

Jun 12, 2019 · In “Rutherford, transmutation and the proton”, you’ll find an account of the historical events leading to Ernest Rutherford’s discovery of the proton, published in 1919.
How did Ernest Rutherford discover the proton? What was his experiment? Question Date: 2016-02-03. Answer 1: Ernest Rutherford bombarded nitrogen atoms with helium nuclei (alpha particles), and hydrogen atoms (protons) were formed as a result. From this, he concluded that nitrogen nuclei contained protons. Note from ScienceLine moderator:
May 8, 2019 · The events leading to Ernest Rutherford’s discovery of the proton, published in 1919. Nuclear giant Ernest Rutherford in Canada in 1907. Credit: Artist R Mathews; McGill University. In his early days, Ernest Rutherford was the right man in the right place at the right time.
They quickly found in 1919–1920 that nitrogen and other light elements ejected a proton (Rutherford said “a hydrogen atom” rather than “a proton”) when hit with α (alpha) particles. Rutherford and his collaborators saw scintillations – flashes of light – when the high-speed particles hit a zinc-sulfide screen in a darkened room.
He discovered and named the atomic nucleus, the proton, the alpha particle, and the beta particle. He discovered the concept of nuclear half-lives and achieved the first deliberate transformation of one element into another, fulfilling one of the ancient passions of the alchemists. Beginnings.
