because it likes its vegetables
When it is burnt it starts burning as a green, then towards the end as the electrons start to settle right down it starts to burn orange with a touch of green.
The flame color of barium burning in oxygen is green.
Barium produces a light or apple green flame when held in a hot clean burning gas flame. it could be confused with the different green flames produced by copper, boron, molybdenum, antimony, tellurium, thallium, phosphorus and others.
Barium ions give off a green colour when heated in a flame.
The element is barium. When barium is heated in a flame test, it produces a distinct green flame color due to the emission of specific wavelengths of light. Barium is an alkaline earth metal found in Group 2 of the periodic table.
When it is burnt it starts burning as a green, then towards the end as the electrons start to settle right down it starts to burn orange with a touch of green.
Some Yule logs that are available commercially have green and red flames when they burn. The chemicals that cause the colored flames are barium and strontium.
The chemical that makes a firework green is typically barium compounds, such as barium chloride or barium nitrate. When the firework is ignited, the heat causes the barium to emit green light.
Barium chloride, or any other barium salt, should burn with a green flame. When a barium salt is burned, the thermal energy is transferred to the outer electrons of the barium ions. They gain enough energy to excite them to a higher energy level. They then drop back to their ground state, releasing energy. This energy corresponds to a wavelength of light, which is emitted from the ion. This wavelength corresponds to green light, hence the green flame observed.
The color of barium in flame is pale green.
Barium compounds, such as barium chloride, are often used in fireworks to produce a green color when burned. When barium salts are heated, they emit green light due to the energy absorbed and then released by barium ions.
It is the characteristic colour of a barium flame.

What color? Green. Sources? See below. http://www.colourlovers.com/blog/2008/02/25/the-magical-colors-of-fireworks/ http://chemistry.about.com/library/weekly/aa062701a.htm
Barium compounds are commonly used in fireworks to produce a bright green color. Barium nitrate and barium chlorate are two examples of barium compounds that are utilized to achieve the desired green color in fireworks.
The flame of barium nitrate typically produces a pale green color when burned. This green color is a characteristic flame test color for barium compounds.
Barium nitrate is used in fireworks as a green colorant for the flames. When burned, it produces a bright green light due to the barium ions emitting specific wavelengths of light. This gives fireworks their characteristic green hue.
