Ernest Rutherford: Unlocking the Secrets of the Atom

Ernest Rutherford (1871–1937) is known as the “Father of Nuclear Physics.”
In 1899, he discovered two types of radiation: alpha and beta particles.
His gold foil experiment (1909) showed atoms have a tiny, dense nucleus at their center.
This overturned the “plum pudding” model, reshaping our view of atomic structure.
Rutherford coined the term nucleus to describe the atom’s central core.
In 1911, he proposed the nuclear model of the atom, with electrons orbiting the nucleus.
He discovered that atoms could be split, paving the way for nuclear physics.
In 1917, Rutherford achieved the first artificial nuclear reaction by bombarding nitrogen with alpha particles.
He mentored future Nobel Prize winners, including Niels Bohr and James Chadwick.
Rutherford’s breakthroughs opened the door to nuclear energy, medicine, and our modern understanding of the atom.
