Krypton
Krypton
The element I’m researching is krypton. The name krypton comes from the Greek word
kryptos meaning “the hidden one.” Krypton is located in the fourth position in the noble gas
section of the periodic table. Krypton’s atomic number is thirty-six. It is in the fourth row and
last column of the periodic table.
Krypton is a tasteless, odorless, and colorless element. It occurs in small amounts in the
atmosphere. It is isolates itself by partially distilling liquefied air. Krypton is sometimes used
with other elements to make fluorescent lamps. Krypton can make a clathrates when mixed
with water. Krypton can and might be used in lighting and photography. Krypton plays an
important role in gas lasers. Krypton was found by Sir Williams Ramsay in 1898. Sir William
Ramsay found Krypton in Britain. He found it by looking at the residue left after liquefied air
was evaporated. The amount of krypton in the atmosphere is unknown. Krypton is formed in
the crust of the Earth when uranium and other elements that are radioactive break down.
Krypton does not react chemically.
Krypton combines with Fluorine. Krypton is found in the compound Krypton difluoride
and Krypton tetrafluoride. Krypton is combined with other elements but they are only lab
tested, they are not used for anything. Krypton is used in various types of lamps. It is used in
airport runway lights. It is also used in movie projectors and slide projectors. Krypton is used
to make neon lights. Krypton is used with Argon in fluorescent lamps that are energy saving
lights. Krypton is used in photographic projection lamps. When combined with other gases
krypton emits a greenish yellow light. Krypton is mixed with xenon to make incandescent
lights. These lights are brighter and emit a more blue light than usual lights. Krypton emits are
white light. Lights used for advertising are usually all Krypton based even though the letters
may be in another color. Krypton a much more powerful red light than neon and is used for
high powered lights in laser light shows. In laser lights the have krypton and a mirror to capture
the red light only. Krypton is used with fluorine to make a krypton fluoride laser. This laser is
used in nuclear fusion. Liquefied Krypton is used to make quasi-homogeneous electromagnetic
calorimeters. Krypton is also used in older jet engines. Krypton is used in MRIs to image airways.
Krypton is used with xenon in ventilation.
The melting point of Krypton is -157.2 degrees Celsius. The boiling point for Krypton is -153.4
degrees Celsius. The crystal structure of Krypton is cubic. Krypton glows a pale mauve color when it is
electrified. Krypton has a high thermal conductivity. Krypton is also called an inert gas. Krypton is a
monatomic gas.
