7. Occurrence in nature:
•Earth’s atmosphere consists of around 0.0001
percentage of krypton.
•Krypton is obtained by evaporating liquid air till now.
Krypton is also formed, when uranium or other
radioactive elements breaks down in Earth’s crust..bbbnbmr,gm:sdaepso,cnsme

it is named after a greek word “Krypto”, means “hidden”.
•Krypton behaves as Neon at very high temperatures but
glows purple instead of red.
•Krypton discharges a greenish yellow glow, when it is
mixed with other gases.
•Krypton is present rarely on earth, but in stars in
abundant quantity like sun.
