Facts
Interesting Facts
- 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.
- Heat capacity of Lithium is very high.
- Lithium inflammable and highly explosive metal, hence it has to be stored properly.
