Aluminum (American English) or aluminium (British English[1]) is a chemical element, having the chemical symbol Al. Its atomic number (the number of protons) is 13. It has a standard atomic weight of 26.98154 g•mol −1, and is typically found as a solid in its elemental form.
Aluminum is considered to be a member of the "Post-transition metal" class of element. At a pressure of 101.325 kPa, it has a boiling point of 2519 °C, and a melting point of 660.32 °C. It is the most reactive post-transition element metal and the most abundant metal in the Earth's crust.
