Noble Gases

Helium, Neon, Argon, Krypton, Xenon, Radon

Helium

Helium can be absorbed into the body. SIde Effects: Dullness, Headache, and Dizziness.


On loss of containment, this gas can cause suffocation by lowering the oxygen of the air in certain areas.


Helium was found in space by Pierre Janssen, and Norman Lockyer in 1895.


Boiling Point:

(-268.9°C)


Melting Point:

(-272.2°C)

Neon

Neon’s largest use is being used in neon signs.


Helium and neon are used in the making of gas lasers.


Noble gases don’t have any valence electrons.


Boiling Point:

(-246.1°C)


Melting Point:

(-248.6°C)



Argon

Argon makes up 1% of the Earth’s Atmosphere.


Argon causes no ecological damage to the environment.



Boiling Point:

(-185.8°C)


Melting Point:

(-185.8°C)


Krypton

Krypton is used with Argon as a gas in fluorescent lights.


Used in some photographic flash lamps for taking high-speed pictures and lamps.


Boiling Point:

(-153.2°C)


Melting Point:

(-157.4°C)

Xenon

Xenon has no long term environmental effects but if it is at a temperature of -244 degrees it will freeze organisms on contact.


Boiling Point:

(-108.1°C)


Melting Point:


(-111.8°C)



Radon

Radon is radioactive, rarely occurs in a natural environment.


Most Radon compounds found in the environment are caused by human activity.


Radon enters the environment through the soil, through uranium and phosphate mines, and through coal combustion.


Boiling Point:

(-61.85°C)


Melting Point:

(-71.15°C)
