Aluminum

Aluminum 1. Name & symbol: (*1) Aluminum / Al 2. Atomic number & weight: (*1) 13 / 26.98 3. Common isotope: (*2) Aluminum isotopes’ mass numbers range from Al-23 to Al-30. Only Al-27 (stable isotope) and Al-26 (radioactive isotope) occur naturally. 4. Group number: 13 5. Common uses: (*3) Aluminum has many uses ranging from kitchen utensils to the siding used for decorating the outside of a house to various other industrial applications. (*4) -cans and foils -kitchen utensils -outside building decoration -industrial applications where a strong, light, easily constructed material is needed -although its electrical conductivity is only about 60% that of copper per area of cross section, it is used in electrical transmission lines because of its lightness and price -alloys are of vital importance in the construction of modern aircraft and rockets -aluminium, evaporated in a vacuum, forms a highly reflective coating for both visible light and radiant heat. These coatings soon form a thin layer of the protective oxide and do not deteriorate as do silver coatings. These coatings are used for telescope mirrors, decorative paper, packages, toys, and in many other uses 6.
