8. Unusual facts of krypton?
• Krypton was discovered partially by accident, that is why
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.
