Contributor To The Atomic Theory
Experiments, Contribution, and Spiritualism
William Crookes's experiments with cathode rays and his Crookes' Tube helped contribute to the discovery of the electron, thereby contributing to the Atomic Theory. His experiments also led to the discovery of a new element called thallium. Crookes even developed an interest in Spiritualism and studied it scientifically. Based on this study he became a believer in it.
