Exploring the Wonders of Gallium

Gallium is a soft, silvery blue metal with the chemical symbol GA and atomic number 31. Predicted by Mendeleev and discovered by Lecoq, gallium is used in semiconductors like gallium nitride and gallium arsenide, which are alternatives to silicon in electronics. These compounds are crucial in LEDs, laser diodes, and solar cells. Gallium also forms low melting alloys like Galinstan, used in thermometers, and is applied in creating reflective surfaces and mirrors.
