I am the chemical element known as Krypton. I
can also be referred as Kr. I will be telling you
about my history, my properties, my family and my
occurrence. I will also be telling you about my
uses and ores, also the analytical methods based
on me.
I received the name krypton from the Greek word
"hidden" because I was hiding for so long,
undetected. I am from a rare group of gases called
noble gases. The other noble gases are helium,
xenon, neon, argon and radon. I was discovered
in England in 1898 almost 100 years ago by Sir
William Ramsey and Morris W. Travers. They
found me in the less volatile part of inert-gas
mixture left after oxygen had been chemically
removed from a sample of air. I am about one
millionth of the earth's atmosphere. Only about 2 x
10-8% of the weight of the earth am I. I am a
colorless, odorless and tasteless gas. My atomic
number is 36. My atomic weight is 83.80. My
melting point is -157.20°C or -251.5°F. My gas
density at 0°C is......
