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.
Gallium is a silvery metal that can be liquid near room temperature and is used in LEDs and nuclear medicine. Learn about its properties, history, isotopes, compounds, and more on this comprehensive web page.
