Krypton: Chemical Elements Of The Periodic Table

Although when you first hear the word Krypton you just might automatically think of the planet in the Superman comics. Krypton is a chemical element of the periodic table. The periodic table has about one hundred and eighteen elements. Krypton is number thirty six in the periodic table it is in group eighteen period four. It is a part of the noble gas series. Its atomic number is thirty six and its atomic mass is eighty three point seven nine eight. It has forty eight neutrons in its most sufficient isotope that are in four different electron shells. It was discovered by Chemist Sir William Ramsay and Morris Travers in the year eighteen ninety eight. It was found in London when Sir William Ramsay made a statement that there had to be more elements because there was a gap in the Periodic Table of Elements that are like Krypton in being noble gasses helium and argon. Knowing this he was determined to find the elements that where needed to fill the gap so he did a little research. He collected information about how one element could possibly hide another element. So he thought maybe there is a new element hiding in his previously discovered element Argon. Argon is also in group eighteen on the periodic table which is in the noble gas series like Krypton. They then proceeded to extract a large amount of argon from the air then they liquefied it then
distilled it to separate fractions of it to see if there where traces of a new element. But this wasn’t enough to prove if a trace of a new element was there so they evaporated most of it leaving only one hundred milliliters of it. Sir Ramsay had a feeling that it would be improbable of a new gas lighter then argon would be there but an idea came to him that there might just be a new heavier gas. With this idea in his mind he removed oxygen and nitrogen from the gas using red-hot copper and magnesium he then placed a small sample of the remaining gas into a vacuum tube and applied high power energy to see the gasses spectrum. His results where that there was Argon present which was known and then a green and yellow line which was never seen before. They then measured the scale of the gasses specific heat at the same pressure to its specific heat and at a constant volume it was one point sixty-six this number could only be found if the new gas only had single atoms which proved that it couldn’t be a compound which meant it was a new found element. Xenon was found this same exact way a few weeks later. Its name started from the Greek word “kryptos” which means hidden. He decided to name it Krypton because of the origin of the word kryptos because this new noble gas was hidden in the element Argon. That is how the noble gas Krypton was discovered.
Krypton does not have many uses but the ones it does have are very useful. One of the main commercial uses for Krypton is flash photography because the flash gives off a really high temperature of heat. Krypton surrounds the heat and prevents anything from burning up. Another main commercial use is for very distinct kinds of lamps, when an electrical current is passed through this gas it gives off a very bright light. Krypton is also used in fluorescent lights, it seems to glow very well. .Krypton used to be how we measured the length of a meter. Scientists figured that a length of a meter was the orange-red spectral line of the krypton isotope 86Kr. Another use for krypton is for lasers since it’s a non-reactive gas it’s commonly seen in a laboratory you can’t just buy it as an everyday thing at the store. This gas is also used in making neon lights they are kind of like fluorescent lights but they give off different colors depending on what gas is in the bulb. If the bulb contains krypton it’s going to give off a yellow light. By now you should know that krypton gives off very bright light. With this resource we use krypton for airport runway lights because you can see the light in any weather. Lastly krypton is used for insulation. It is placed in a window pane and it creates heat.
Krypton’s chemical properties are: Atomic number: thirty six, Atomic mass: eighty three point eighty amu, Density: three point seventy-three grams/centimeters cubed, Number of Protons/Electrons: thirty six, Number of Neutrons: forty eight, Isotopes: fifteen.
Krypton’s physical properties are: Melting point: negative one hundred and fifty seven point two Degrees Celsius, Boiling point: Negative one hundred and fifty three point four Degrees Celsius, it is also colorless, odorless, and tasteless.
Facts about the noble gas Krypton:
• In total it has thirty one isotopes which five are stable and the others are
radioactive.
• It is produced in the earth’s crust when the elements thorium and uranium decay.
• When krypton is ionized it creates a bright white light that is commonly used in movie/film projectors.
• This gas is inert which means that it doesn’t have the ability to react.
• Out of the twenty six radioactive isotopes one of them when combined with phosphorus it creates material that glow in the dark.
• It also can be used to see the blood flow of a person’s body when it is inhaled it is absorbed into the blood stream this pathway can be seen if you hold a detection device over the person’s body.
• The isotope Krypton-eighty five in the atmosphere can detect nuclear weapons.
• It is one of the Earth’s rarest and expensive gasses.
• One of Krypton’s isotopes Krypton-eighty three can be used in medical MRI technology
• The Krypton definition has changed several times the most recent one was in ninety eighty three.
• Krypton was the gas left over when oxygen, nitrogen, argon, helium, and water had been removed from the air.
• At one part per million it is found in the Earth’s Atmosphere.
• Since Krypton is a noble gas all of the Earth’s original amount of Krypton have stayed the same.
• Krypton is known to replace the breathable air depriving you from the air which may cause unconsciousness or death.
In conclusion Krypton is a very useful element. It is very bright and is used for many things. Some of its cons are that you cannot breath it.
