This instability is what drives the process of corrosion and it results from the fact that a refined metal is continually trying to revert to its natural state the mineral Some metals do this faster than others The Galvanic Series ranks corrosion te IJCAES S PECIAL I SSUE ON B ASIC , A PPLIED & S OCIAL S CIENCES , V OLUME III, J ANUARY 2013 [ISSN: 2231 - 4946] 38 | Page - Hakim in the Drama al - Sultan al - Ha’ir (The Sultan’ METAL CHEMISTRY.

State . the less reactive metals, including gold, silver and copper, are found uncombined in the Earth’s crust and the more reactive metals have to be extracted from their ores. The determination of heavy metals related to monitoring of the environment has gained increasing interest. Our new method enables one to carry out such monitoring unattended and automatically on site, consequently the current control of short time effluents can be done. Traditional methods by collecting samples to be brought to well equipped laboratories will render this impossible because only a discrete number of samples can be collected.. . by Head of trade restrictions, . currency and export control .

They are a series of chemical elements which have similar trends and properties. Alkali metals are so called because when they react with water alkalis (strong bases that can neutralize acids) are formed..
