Whats it used for?

Gallium is a critical metal mostly used in high performance electronics, power supplies, and medical imaging machines. While it is famous for melting in your hand, its industrial value lies in its ability to outperform silicon in electronics machines.
History Of Gallium
Gallium, identified by chemical symbol Ga and atomic number 31, was discovered spectroscopically by French chemist Paul-Émile Lecoq de Boisbaudran in 1875 while examining zinc blende ore. It famously validated Dmitri Mendeleev’s 1871 prediction of eka aluminum.
Known for its low melting point of≈29.76∘𝐶), it is a critical material in modern semiconductors and electronics.
