Noble gas essay

It is located in group 18 and period 4 on the periodic table e (Meadows). 36 protons are found within the nucleus of an atom of krypton, thus it has an tat mice number of 36 (Meadows). Krypton’s name was derived from the Greek word krypton mean Eng “hidden”, and the use of this word roots from the process that it took to discover krypton: it was “dinner’ in the residue after liquid air had nearly boiled away” (West and Castle BIB). Wit h its historical background, special properties and multitude of uses, krypton is a chemical el meet that should not be overlooked.

In 1 898, Sir William Ramsey and Morris William Traverse of university College London, England first isolated the element krypton in pure form (Stewart). Ra Mays previous discoveries of helium and argon are what inadvertently led to the discovery of krypton (Stewart). Around the time of the discovery, Ramsey and Traverse planned to extract a lard GE volume of argon from the air, liquefy the argon, and use distillation to discover a lighter e element that would fit between helium and argon (Stewart).

Since the two chemists had little expel irenic with liquid gases, they used liquid air to practice the procedure (Stewart). To begin, Rams ay and Traverse evaporated the majority of the liquid air and left just 1 mm’ remaining (Stewart t). Since they had created a heavy gas sample, they knew that it was quite unlikely that the light ere element they were searching for would be present (Stewart). Despite this, they continued to analyze the light spectrum of their sample in hopes of discovering something new; this decision n to proceed is what De to the discovery of krypton (Stewart).

After removing oxygen and nitrogen from the gas with the use of copper and magnesium, the chemists examined the gas’s spectrum within a hightailed vacuum tube (Stewart). Besides the anticipated presence of argon , two new spectral lines, green and orange in color, were also observed; these lines represented a new element, later named krypton after being removed from its ‘hiding place” within liquid air (W east and Castle 822; Stewart). Following the discovery of the inert gases such as krypton, Ram ay was given the Nobel Prize for Chemistry in 1904 (Stewart).

Along with its discovery, krypton was used and documented in other points in history. During the Cold War (194791 ), radioactive krypton was used to approximate t he nuclear production of the Soviet Union (“Krypton”). Krypton, one of its radioactive is topes, is produced by all nuclear reactors, so one was able to calculate the amount of k raptor being emitted by the USSR by subtracting the amount that came from the reactors i n the U. S. And Europe from the total amount of krypton in the air (“Krypton”).
