Crystals of gallium joined together

Gallium (chemical symbol: Ga) is chemical element 31 on the periodic table.

Gallium is a metal, but is has some unusual properties. If it is held in a person's hand, it will melt. Gallium does not conduct electricity well, and is known as a semiconductor. That means gallium can be used in computers to make them work. It is very shiny, so it is used to paint mirrors when melted.
