Interesting Facts
- Einsteinium is the transuranic element found in US.
- Only 0.01 mg of Einsteinium was synthesized in 1961.
  
- 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.
