Sir William Crookes Discovers Thallium

March 30th, 1861 163 years ago

In 1861, Sir William Crookes announced the discovery of thallium, a new chemical element. He identified it through his studies of uranium minerals, utilizing a spectroscope to analyze the emitted light and detect the unique spectral line characteristic of this element. Crookes's meticulous experimentation led him to isolate thallium, which he named after the Greek word for green, 'thallos', reflecting the bright green line in its spectrum. This discovery expanded the periodic table and contributed to the field of chemistry.
