Group 0- Noble gases

Why are Group 0 elements called noble gases?

They are unreactive due to a full outer shell of electrons.

What are the trends in boiling points in Group 0?

Boiling points increase down the group.

Why do noble gases have low reactivity?

They have a stable electronic configuration with a full outer shell.

How is helium used in everyday life?

In balloons and airships because it is lighter than air and non-flammable.

Why is argon used in light bulbs?

It is inert and prevents the filament from oxidizing.

How does xenon differ from helium in terms of density?

Xenon is much denser than helium.

Why does the boiling point of neon differ from argon?

Larger atoms like argon have stronger intermolecular forces.

What role does radon play in health concerns?

It is radioactive and can be harmful in high concentrations.

How are noble gases used in neon signs?

They emit light when electricity passes through them.

Which noble gas is used in cryogenics?

Helium, due to its extremely low boiling point.

Why is helium preferred over hydrogen for filling balloons?

Helium is non-flammable.

Why do noble gases not form compounds easily?

They already have a stable electronic configuration.

What happens to atomic size as you go down Group 0?

It increases due to more electron shells.

How is krypton used in medicine?

In lasers for eye surgery.

What is the main industrial use of argon?

As a shielding gas in welding.
