Polonium - Element information, properties and uses

Polonium has a position in the periodic table that could make it a metal, a metalloid or a nonmetal. It is classed as a metal as its electrical conductivity decreases as its temperature rises. Because of this property it is used in industry to eliminate dangerous static electricity in making paper or sheet metal.

Description: Aluminum or aluminium is a silver-white metal, very light in weight (less than three times as dense as water), yet relatively strong. Because aluminum is ductile, it can be drawn into wires or pressed into sheets or foil. It is the most abundant metallic element, and the third most abundant of all elements in the Earth''s crust, making up 8% of the crust by weight.

Silicon Metal | CRM Alliance

Silicon metal (syol Si), in its pure form, is a grey metallically lustrous metalloid element. Metallurgical grade silicon is known as silicon metal because of its lustrous appearance. Silicon is used mainly in the manufacture of silanes and silicones, as a “hardener” or alloying element to produce aluminium alloys, and in the manufacture
