Rare Gases

This quiz introduces the rare gases, also called the noble gases, across 12 questions.

You will work through items like Which gas is used to inflate balloons? and Kr is the element symbol of ___., plus a handful of true or false statements.

One fact worth holding onto is that these gases sit together in Group 18 of the periodic table and barely react with anything, which is why they earned the "noble" label. One of them, though, is actually radioactive.

Recommended level: beginner to intermediate.
