Geiger–Marsden experiment
The Geiger–Marsden experiment, also known as the gold foil experiment, was a landmark early 20th-century physics experiment that revealed the existence of a small, dense atomic nucleus and led to the development of the Rutherford model of the atom.

Franck–Hertz experiment
The Franck–Hertz experiment is a landmark early-20th-century physics experiment that provided direct evidence for the quantization of atomic energy levels, supporting the Bohr model of the atom.
-
C.
Trouton–Noble experiment
The Trouton–Noble experiment was an early 20th-century test of the luminiferous aether that searched for a torque on a charged capacitor in motion and, by finding no such effect, provided support for the emerging theory of special relativity.
