Root Explanation

Krypton comes from the Greek word "kryptos" (meaning hidden). The name reflects the element's elusive nature, as it is a noble gas that is colorless, odorless, and does not readily react with other elements.

Memory Tip

Think of the Greek word for 'hidden' — that's why krypton is a gas that is not easily seen or detected.
