Aluminum (or aluminium) is a soft, lightweight, silvery metal. It is an element in the boron group on the periodic table of elements, with the symbol Al and atomic number 13. On the earth's crust, aluminum is the most abundant metal, and the third most abundant of all elements on the earth's crust, after oxygen and silicon. It accounts for 8% of the weight of the Earth's solid surface. Because aluminum is a highly reactive metal, it doesn't occur in nature in a pure form. Aluminum forms a...

Manganese is a chemical element in the periodic table that has the symbol Mn and atomic number 25. Notable characteristics Manganese is a gray-white metal, resembling iron. It is a hard metal and is very brittle, fusible with difficulty, but easily oxidized. Manganese metal is ferromagnetic only after special treatment. The most common oxidation states of manganese are +2, +3, +4, +6 and +7, though oxidation states from +1 to +7 are observed. Mn2+ often competes with Mg2+ in...
