Gallium
From Simple English Wikipedia, the free encyclopedia

Crystals of Gallium (the shapes you can see in the silver coloured block) joined together. They are very pure.
Gallium (chemical symbol: Ga) is chemical element 31 on the periodic table.
Gallium is a metal, but is has some interesting properties. If you hold gallium in your 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.
Gallium is not dangerous to people because there is not much of it on the Earth.
