Gallium, discovered in 1875 by French chemist Paul-Émile Lecoq de Boisbaudran, was significant because it was the first element predicted by Mendeleev's Periodic Table before its discovery. Its existence confirmed the validity of the periodic law and the predictive power of the periodic table. Additionally, gallium's unique properties, such as its low melting point and ability to remain liquid just above room temperature, have led to various applications in electronics and thermometers.
