class: metal
family: boron family
origin of name: Greek- thallos (green twig)
Discovered by: Sir William Crookes
the colour of gallium when in a powder state is silvery, in a liquid state it is almost always mixed with other substances so the original colour is unknown
Below room temperature, gallium is a solid, but soft, silvery metal. At slightly above room temperature, gallium melts into a silvery, metallic liquid.
