Beryllium is a chemical element with the symbol Be and atomic number 4. It is a relatively rare, strong, lightweight, brittle, gray-white alkaline earth metal. Beryllium and its alloys are used in aerospace and defense applications, electronics, automotive components, and medical equipment. Beryllium is toxic and carcinogenic.

Beryllium was discovered in 1798 by Louis Nicolas Vauquelin. It was first isolated as a metal in 1828 by Friedrich Wöhler and Antoine Bussy independently. Beryllium is found in minerals such as beryl and bertrandite. The United States, China, and Kazakhstan are the leading producers of beryllium.

Beryllium has a high melting point, high stiffness, and is lightweight. These properties make it useful in applications where strength and lightness are critical. Beryllium alloys, such as copper beryllium, are used in electrical connectors, springs, and tools that require non-sparking properties. Its transparency to X-rays makes it useful for windows in X-ray tubes and detectors.

Exposure to beryllium dust or fumes can cause berylliosis, a serious lung disease. Strict safety precautions are necessary when working with beryllium. Proper ventilation, respiratory protection, and hygiene practices are essential to minimize exposure risks. Research continues into new applications for beryllium and its compounds, balancing its unique properties with the need for safety.
