When was it discovered? Who discovered the element?

Krypton got its name from the Greek word for 'hidden', kryptos.

Krypton was discovered on May 30, 1898 by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, while studying liquefied air. Small amounts of liquid krypton remained behind after the more volatile components of liquid air had boiled away.

What does the element look like?

It turns out that you look at krypton every day, although you may not actually see it. Krypton is one of the gases that make up the earths atmosphere. Krypton is a colorless, odorless gas that rarely reacts with other elements. A container full of krypton gas looks just like a container full of air. It isn't very exciting. Solid krypton is white and crystalline.

Why is it important to preserve or keep creating this element? What is it used for?

The high cost of obtaining krypton from the air has limited its practical applications. Krypton is used in some types of photographic flashes used in high speed photography and in high-powered, flashing airport runway lights. Some fluorescent light bulbs are filled with a mixture of krypton and argon gases. Krypton is also combined with other gases to make luminous signs that glow neon.

A reason we should preserve Krypton is because it has many uses for us. It may not be as important as something like oxygen but it still has many uses that we will need. It is already limited to us so it would be even harder to preserve it, which is why we should start soon. It helps us with photography, lighting, and even to detect nuclear production.

Interesting Facts

The earths atmosphere is about 0.0001% krypton

Krypton is obtained by distillation from liquid air despite being one of the rarest gases in the Earth’s atmosphere, accounting for only 1 part per million by volume.
