Did You Know?
Krypton is a 'Noble Gas,' meaning it’s super chill and rarely reacts with other elements. It basically minds its own business, unlike those drama-prone reactive elements!
Its name comes from the Greek word 'kryptos,' meaning 'hidden.' A perfect name for an element that’s colorless, odorless, and a tiny fraction of our atmosphere!
Before 1983, the official definition of a 'meter' wasn’t a metal bar; it was based on the orange-red spectral line of a specific krypton isotope! Talk about setting the standard!
