Gallium is a silvery-white metal used in high-speed semiconductors and LEDs in the form of gallium arsenide (GaAs). The pure metal is somewhat brittle, has a very low melting point of 29.78° Celsius (85.2° Fahrenheit). It will melt in your hand if held long enough, but this is not recommended because it stains hands and is difficult to get off.
It is used in some thermometers in the form of an alloy of gallium, indium, and tin. The reason this alloy is used in thermometers is because it’s a liquid at room temperature and therefore can be used as an alternative to mercury, which is poisonous.
