Example Question #1 : Resources And Energy

Which noble gas, commonly used at children's birthday parties, is currently considered to be in limited supply?

Possible Answers:





Correct answer:



Helium is frequently used in balloons at parties. It is lighter in mass than the surrounding air, allowing it to "float" upwards. As a noble gas, helium is also largely inert and has numerous practical purposes in chemistry due to this property.

Beginning in 2013, the amount of helium used began to far exceed the supply, resulting in a helium shortage.

Neon and argon are noble gases (like helium). Hydrogen is not a noble gas, and is actually highly reactive.
