The heaviest element yet made is oganesson. Scientists

think it would be solid at room temperature, but it may really

be an unreactive, noble gas. However, only a few atoms

have been created so far, so its properties are not well

understood. Oganesson was first produced by a team of

Russian and American scientists who smashed californium

and calcium atoms together at the Joint Institute for

Nuclear Research in Dubna, Russia. The element was

named after Yuri Oganessian, the leader of the team.

This kit collects radon from

the air so the amount of the gas

in the area can be measured.

The muddy water

from volcanic springs

contains radon.

These pipes draw water containing

radon from deep under the ground,

and this is then used to power the plant.
