Essay, Research Paper: Krypton

The element that I have chosen in . The people
who discovered it are known as Sir William Ramsay and
Morris William Travers. Sir William Ramsay and Morris William
Travers were looking for new gases in the air when the
discovered krypton (Kr). They called it krypton which is
Greek for 'hidden'.
Ramsay and Travers discovered this gaseous element in
1898. They discovered it by collecting residues that were
left after their experiment. While looking for new gases
they mainly found oxygen and nitrogen which had already
been discovered. One day the residue that they had found
was deviant. The had unearthed KRYPTON!
Krypton is known as one of the argonons. It is
colorless, odorless, tasteless, and also monoatomic. Krypton
is one of the six noble gases which occupy Group 8A of the
periodic table. They are remarkable for their unreactivity,
but there are two gases that it does react with and they are
fluorine and chlorine, halogens from Group 7A.
Krypton is used as a source of light in incandescent
and gaseous-discharge lamps.
I can be used in aluminum welding as a "blanket" of over the
metal to keep it from reacting violently with oxygen or
nitrogen. However, it comes with a mighty price at $30/liter
the average person cannot afford to much of it.
Krypton has an atomic number of 36 and a density of
3.74g/cm cubed. It melts at -157.2 degrees Celsius and boils
at -153.4 degrees Celsius. It has a cubic crystal structure
and is classified as one of the noble gases. It has 36
protons/electrons and 48 neutrons.
