These condensers use tubes that are usually made of stainless steel, copper alloys, or titanium depending on several selection criteria (such as thermal conductivity or corrosion resistance). The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus. The atomic radius for manganese is 127 pm whereas for magnesium is 160pm. Plutonium is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The chemical symbol for Chlorine is Cl. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. 1) You may use almost everything for non-commercial and educational use. Tin is a post-transition metal in group 14 of the periodic table. These are so called because their oxides and hydroxides are alkaline in nature and these metal oxides are found in the earth’s crust*. 0. In nuclear industry gadolinium is commonly used as a neutron absorber due to very high neutron absorbtion cross-section of two isotopes 155Gd and 157Gd. Lead is soft and malleable, and has a relatively low melting point. The chemical symbol for Potassium is K. Potassium was first isolated from potash, the ashes of plants, from which its name derives. Atomic Radius. The atomic radius of a chemical element is the distance from the centre of the nucleus to the outermost shell of an electron. Consequently, the smallest atom is helium with a radius of 32 pm, while one of the largest is caesium at 225 pm.
