Answer 2

Here is a list of the inert gases and their common uses:
You can use this list to make the chat required here by simply putting two columns of:
a) Inert gas
b) Uses
i) Helium - due to its small density ( it is much lighter than air), it is used to fill air balloons and blimps. 
ii) Radon - radon is used medically to destroy malignant growths. Radon emits gamma rays that are harmful to these malignant cells.  
iii) Neon - when electric current is passed through neon gas under low pressure, it gives off a red glow. This is the reason why neon is used in advertising signs and glow lamps. 
iv) Argon - argon is used in filament bulbs to protect the filament from burning as it prevents the oxidation of the metal used in making the filament. 
v) Xenon - xenon is used in photography in flash bulbs because of its ability to emit instant intense light. It is also used in fluorescent bulbs and lasers.
