Etymology
The name thallium comes from the Greek word 'thallos', meaning 'green shoot' or 'twig'. This reference is due to the bright green spectral line emitted by the element when it is vaporized. Thallium was discovered in 1861 by English chemist William Crookes during his work on the properties of the newly developed spectroscope. Crookes first identified thallium as part of a method to isolate the element from other substances. The element was originally used in various industrial applications, but its high toxicity led to its limited use in certain products over time, especially in consumer goods. As understanding of its health risks grew, there was a shift towards finding safer alternatives.
