Gallium is the thirty first element on the periodic table, giving it thirty one protons and electrons. It cannot be found as a free element and is one of the few metals that is a liquid near room temperature (gallium has a melting temperature of 29.8 °C or 85.6 °F).
On the periodic table, it is often classified as a post transition metal. These metals are generally soft, with poor mechanical strength and low melting points. Metals typically have good thermal and electrical conductivity and usually form cations rather than anions.
Gallium is a soft, silvery and brittle metal that is easily alloyed with many metals. It is a highly anisotropic element with two stable isotopes.
