Answer 1

Ernest Rutherford discovered that an atom is made up mostly of empty space, with a dense nucleus at its center. In his famous gold foil experiment conducted in 1909, Rutherford found that while most alpha particles passed through the gold foil with little deflection, a small number were deflected at large angles. This led him to conclude that the atom consists of a small, positively charged nucleus containing most of its mass, surrounded by a cloud of negatively charged electrons. This model significantly changed the understanding of atomic structure at the time.
