Gallium ([Ar]3d104s22p1) (CAS 7440-55-3) is grayish when solid: tin or silvery colored when molten. It has one of the longest liquid ranges of any metal, has a low vapor pressure even at high temperatures, and shows a tendency to remain in a supercool state. Gallium is one of four metals that can be molten at room temperature. It has a higher density as a liquid than as a solid. Gallium can be alloyed with most metals and is frequently used as such to reduce the melting point.
