Facts
Interesting Facts
  • Lanthanum metal is highly malleable, ductile and sectile.
  • If exposed to air Lanthanum metal oxidizes rapidly.
  
  • Aluminum’s abundance percentage is more as it is found in more than 260 minerals.
  • Pure Aluminum always reacts with oxygen rapidly.
  • It is a good conductor of heat and electricity and used in transmission lines.
