Radon is a ________________.

Explanation:
Radon is a gas under normal conditions. It’s a noble gas—colorless, odorless, and radioactive—that exists as a gas at room temperature, which is why it’s not a liquid or solid in typical environments. Its melting and boiling points are well below everyday temperatures, so it remains gaseous rather than condensing. A plasma is an ionized, highly energetic state, which isn’t the usual form radon takes in homes.
