The gas in a fluorescent light bulb tube is composed of Mercury, along with argon, xenon, krypton or neon. It is important to dispose of the tubes properly after they are used, since mercury can be toxic to people and animals if it is released into the environment.
Mercury and Phosphorous.
Argon produces the color lavender.
Argon & Nitrogen are both toxic.
collecting gas
The gas might be an irritant or toxic. Another possibility unrelated to the gas itself is that the contents of the test tube might unexpected be ejected from the test tube and hit you in the face!
Usually it's mercury vapor.
To limit the current flowing through the fluorescent tube once its gas has ionised.
Conduction works quite well in the gas inside a fluorescent light tube.
six main component of fluorescent tube light
A fluorescent lamp refers to a low pressure mercury-vapor gas-discharge lamp that uses fluorescence in order to produce visible light. It is also called a fluorescent tube.
Not in the way that an incandescent bulb does. A fluorescent lamp uses electricity to excite the particles of mercury vapor in the tube. This excited gas causes a phosphor to glow.
A four tube fluorescent luminaire is just 4 separate fluorescent lamp circuits in one fitting. Look up 'how things work' etc to see a fluorescent lamp circuit.

They are made with fluorescent tubes, bent and compacted to the size of a regular lightbulb. The inside of the tubes is filled with fluorescent gas and phosphor. Electricity passes into the tube and interacts with the gas to make ultraviolet rays and theseinteract with the phosphor and cause it to glow.
Ultraviolet rays can be used as for fluorescent lamps as certain chemicals glow when they absorb ultraviolet. In fluorescent lamps, the sindide of the tube is coated with a white powder that gives off light when it absorbs ultraviolet. The ultraviolet is produced by passing a current through a gas in the tube.
"Normal" light globes use a glowing filament, heated by the current. Flourescent tubes ignite a gas within a tube, using an arc.
