Apariencia: White-gray metallic

Acerca de Berilio

Isolated in principle by Louis Nicolas Vauquelin in 1798, beryllium is a hard, white-gray alkaline earth metal with atomic number 4 and an atomic mass of 9.01. It is light yet stiff, with a density of 1.85 g/cm³ and a high melting point of 1560 K. Two valence electrons in the [He] 2s2 configuration give an electronegativity of 1.57 and a first ionization energy of 900 kJ/mol. Beryllium is transparent to X-rays, which suits it to radiation windows, and its rigidity relative to weight makes it valuable in aerospace materials. Placed in group 2, period 2, the free metal does not occur naturally and must be extracted from minerals.
