Question

Find out the applications of all the inert gases, Prepare a chart and display it in the class

Answer 1

An inert gas/noble gas is a gas which does not undergo chemical reactions under a set of given conditions. The noble gases often do not react with many substances[1], and were historically referred to as the inert gases. Inert gases are used generally to avoid unwanted chemical reactions degrading a sample. These undesirable chemical reactions are often oxidation and hydrolysis reactions with the oxygen and moisture in air. The term inert gas is context-dependent because several of the noble gases can be made to react under certain conditions.

Purified argon and nitrogen gases are most commonly used as inert gases due to their high natural abundance (78.2% N2, 1% Ar in air) and low relative cost.

Unlike noble gases, an inert gas is not necessarily elemental and is often a compound gas. Like the noble gases the tendency for non-reactivity is due to the valence, the outermost electron shell, being complete in all the inert gases.[2] This is a tendency, not a rule, as noble gases and other "inert" gases can react to form compounds

Answer 2

nert gases are considered to be most stable and so they are un-reactive. They are used in many industrial purposes:-

• Helium – It is the lightest of inert gases and so it is used in hot air balloons like weather balloons, airships and other decorative balloons.

• Neon- It is widely used in advertising sign boards in the form of neon glow signs. It is also used for coating inner layer of tube lights.

. Argon – This is widely used in incandescent light bulbs and titanium production. It is also used for coating inner layer of bulbs.

• Krypton – It is widely used in semiconductor manufacturing and other circuit boards.
