What are noble gases known for?
Being very unreactive
How do noble gases appear in terms of color and odor?
They are colorless and odorless.
What does a full outer shell of electrons indicate about an element's stability?
It makes the element stable or inert
How does helium's inertness benefit welding processes?
It prevents oxidation during welding
What makes noble gases stable?
A full outer shell of electrons.
At what temperature can helium cool substances?
−269 °C
What are the main uses of helium (He)?
Balloons: Lifts balloons due to being lighter than air
Welding: Prevents oxidation during welding
Cryogenics: Cools substances to extremely low temperatures (−269 °C)
Why are noble gases unreactive?
They have a full outer shell of electrons
What is the text displayed in the neon sign?
Anit is 40
Why is helium considered ideal for balloons?
Because it is lighter than air
How does argon prevent oxidation during welding?
