Properties of Aluminium

Aluminum (or Aluminum) is a silvery-white in color metal. The chemical symbol of aluminum is Al and it has an atomic number (Z) of 13 in the periodic table. The aluminum name for this metal is derived from the Latin word ‘alumen’, which means bitter salt. Aluminum was discovered in the year 1825 by Hans Oersted, and later Friedrich Wöhler isolated aluminum. It is the most commonly found metal in the earth’s core, which is around 8% of the total core mass. Moreover, it is the third most commonly found element on earth after oxygen and silicon. Electron distribution of aluminum per shell is 2, 8, and 3 with a valency of 3. Atomic weight is nearly 26.9815 u.
