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.

Barium oxidizes very easily in the air.

All toxic compounds of Barium can easily dissolve in water.

Barium carbonate is used to produce a Rat poison and its other compound Barium nitrate is used in fireworks to produce green color.
