Under normal conditions, a thin layer of the hard oxide BeO forms on beryllium’s surface, protecting the metal from further attack by water or air. As a result of this BeO layer, beryllium does not oxidize in air even at 600 o C and it resists corrosion by concentrated nitric acid. Beryllium also has high thermal conductivity and is nonmagnetic

periodic table of the elements | Definition & Groups

2019-3-13 · Periodic table of the elements: Periodic table of the elements, the organized array of all the chemical elements in order of increasing atomic nuer. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.

Alkali - Wikipedia

2019-4-23 · In chemistry, an alkali (/ˈælkəlaɪ/; from Arabic: al-qaly "ashes of the saltwort") is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element. An alkali also can be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline is commonly, and alkalescent
