3 Uses

3.1 Uses & Benefits

Currently known uses of Livermorium metal are limited to research purpose only.

It has a tendency to get tarnished in the open air, but when alloyed with elements like erbium, vanadium, its hardness levels decreases.
Its compounds like Erbium oxide is used in safety glasses of welders and metal workers.
