Barium is a silvery-white metal that can be found in the environment, where it exists naturally. It occurs combined with other chemicals, such as sulfur, carbon or oxygen. Ii is very light and its density is half that of iron. Barium oxidizes in air, reacts vigoroulsy with water to form the hydroxide, liberating hydrogen. Barium reacts with almost all the non-metals, forming often poisouning compounds.

It Gives grassy green colour in flame test. It's ns electrons are excited to higher energy levels and while returning to their ground state the energy absorbed by them are released as visible light.

Metal salts commonly used in firework displays include strontium carbonate (red fireworks), calcium chloride (orange fireworks), sodium nitrate (yellow fireworks), barium chloride (green fireworks) and copper chloride (blue fireworks).

Purple fireworks are typically produced by use of a mixture of strontium (red) and copper (blue) compounds.
