Gallium

About Gallium (Ga)

Symbol: Ga
Atomic number: 31
Atomic mass: 69.723
Element category: Post-transition metal

Gallium is a soft, silvery metal. At low temperatures, gallium exists as a brittle solid. It melts at 29.76 °C (85.57 °F), which is slightly above room temperature. Consequently, gallium is used as a temperature reference.

Gallium alloys readily with most metals. It is used to produce low-melting-point alloys. It also functions as a dopant for semiconductors and is utilised in the manufacture of transistors and light‐emitting diodes.

Gallium compounds produce measurable outputs. Gallium arsenide generates laser light when electricity is applied, while gallium nitride is used for manufacturing blue and violet LEDs and diode lasers.
