Jan 18, 2019 · Learn about gallium, a post-transition metal with a low melting point and various applications. Find out its discovery, properties, uses, sources, and biological role.
Gallium is bluish silver metal. It is soft at STP (standard temperature and pressure), while at low temperature, it acquires a brittle solid state. Gallium also exists in liquid form at temperature more than 29.76 °C. When gallium is held in the hand, it melts and is re-solidified when placed back from hand.
