Aluminum (chemical symbol - Al, from Lat. Aluminum) is a chemical element of the 13th group (according to the outdated classification - the third group of the main subgroup, IIIA) of the third period of the periodic table of chemical elements of D. I. Mendeleev, with atomic number 13.
A simple substance aluminum is a light paramagnetic metal of silver-white color, easily amenable to molding, casting, machining. Aluminum has high thermal and electrical conductivity, corrosion resistance due to the rapid formation of strong oxide films that protect the surface from further interaction.
It belongs to the group of light metals. The most common metal and the third most common chemical element in the Earth's crust (after oxygen and silicon)
