WebMar 19, 2024 · The atom is now considered to be the basic unit of simple substances or elements. He was a schoolteacher who performed many experiments on atoms. His atomic theory had five statements: 1. Atoms are tiny, indivisible particles. 2. Atoms can neither be created nor destroyed. 3. Atoms of one element are all the same. WebThe next groundbreaking experiment in the history of the atom was performed by Ernest Rutherford, a physicist from New Zealand who spent most of his career in England and Canada. In his famous gold foil experiment, Rutherford fired a thin beam of \alpha α particles (pronounced alpha particles) at a very thin sheet of pure gold.
