Chemical Properties:
  1. white to colourless crystals
  2. Aluminum is the most commonly available element in homes and workplaces. Aluminum is readily available for human ingestion through the use of food additives, antacids, buffered aspirin, astringents, nasal sprays, and antiperspirants; from drinking water; from automobile exhaust and tobacco smoke; and from using aluminum foil, aluminum cookware, cans, ceramics, and fi reworks.
