![]() Like aluminum, it forms a thin layer around itself to help prevent itself from rusting when exposed to air. Magnesium is light, silvery-white, and tough. ![]() Chemistry of Magnesium (Z=12) Magnesium is a group two element and is the eighth most common element in the earth's crust.Some Atypical Properties of Beryllium Compounds.It is not abundant in the environment and occurs mainly in the mineral beryl with aluminum and silicon. The element is a high-melting, silver-white metal which is the first member of the alkaline earth metals. Chemistry of Beryllium (Z=4) The name Beryllium comes from the Greek beryllos which is the name for the gemstone beryl.Sections below cover the trends in atomic radius, first ionization energy, electronegativity, and physical properties. Group 2: Physical Properties of Alkali Earth Metals This page explores the trends in some atomic and physical properties of the Group 2 elements: beryllium, magnesium, calcium, strontium and barium.The Thermal Stability of the Nitrates and Carbonates.The Solubility of the Hydroxides, Sulfates and Carbonates.Reactions of Group 2 Elements with Water.Reactions of Group 2 Elements with Oxygen.Reactions of Group 2 Elements with Acids.Includes trends in atomic and physical properties, trends in reactivity, the solubility patterns in the hydroxides and sulfates, trends in the thermal decomposition of the nitrates and carbonates, and some of the atypical properties of beryllium. Group 2: Chemical Properties of Alkali Earth Metals Covers the elements beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr) and barium (Ba).
