OM NAMO CHEMISTRY: General Principles of Extraction of Metals - Blogger

The process of extracting a metal in the state of fusion is called smelting. In this process the ore is mixed with carbon, obtained after the above reactions and heated in suitable furnace. A suitable flux is added during the operation to convert the non-fusible gangue to fusible slag. The metallic oxide is reduced by carbon and the metal may be obtained in the molten state or as vapours which are condensed.

Biological Importance of Alkali and Alkaline Earth Metals

Ionization Energy: Ionization energy or ionization enthalpy is the minimum amount of energy needed to remove electrons from the energy shells of an atom. Alkaline earth metals have low ionization energies because atoms of alkaline earth metals have a big size due to which it is difficult to take out electrons from the energy shell.
