The Full Story
Gallium was discovered in 1875 by Paul-Émile Lecoq de Boisbaudran using spectroscopy. Mendeleev had predicted an element he called eka-aluminum several years earlier, and gallium matched many of his predicted properties remarkably well. The discovery was important because it strongly supported the periodic table and Mendeleev’s periodic law. Gallium is also famous for its very low melting point, which makes it melt in a person’s hand on a warm day.
