Beryllium has a much higher melting point than the other Group 2 elements due to its small size and strong metallic bonding.

  • Some properties of beryllium are:

    • Physical properties: Beryllium is a hard, brittle, steel-gray metal with a high melting point of 1287°C and a boiling point of 2970°C. It is lightweight and has a low density of 1.85 g/cm³, making it useful in aerospace applications.

    • Chemical properties: Beryllium is highly reactive with oxygen and water, forming a thin layer of oxide on its surface that protects it from further oxidation. It reacts with acids to produce hydrogen gas and beryllium salts.

    • Toxicity: Beryllium is highly toxic, particularly when it is inhaled as dust or fumes. Exposure can lead to a range of health effects, including chronic beryllium disease and lung cancer.

    • Electrical conductivity: Beryllium is a good electrical conductor and is used in a variety of electrical and electronic applications, including connectors, switches, and heat sinks.

    • Magnetic properties: Beryllium is diamagnetic, meaning it is not attracted to a magnetic field. This property makes it useful in applications where magnetic interference must be minimized, such as in high-performance electronics and scientific equipment.

    • Isotopes: Beryllium has several isotopes, including the stable isotopes beryllium-9 and beryllium-10, as well as several radioactive isotopes. Radioactive isotopes have been used in a variety of scientific applications, including carbon dating and studies of cosmic radiation.
