Facts

Interesting Facts
  • Manganese is an essential trace element in all forms of life.
  • Manganese metal oxidizes very easily, but it does not fuse that easily.
  
  • 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.
