2 Facts

2.1 Interesting Facts

Beryllium is best anti corrosion metal.

Beryllium is the lightest metal and still it is stronger than steel.

It also finds various applications in Nuclear reactors as a reflector.

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