Gallium is a silvery-white metal used in high-speed semiconductors and [[LED]]s 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.
== Uses ==
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.
