Krypton: The “Super Element”
When you first hear the word “Krypton”, you may think of the fictional planet that
America’s superhero Superman once called home. However, krypton is also the name of a chemical element here on our own planet Earth. Though it is a rare, unreactive noble gas, krypton does play a significant role in today’s world in ways that are unfamiliar to most
(“Krypton”). Krypton is abbreviated by the chemical symbol Kr and is tasteless, colorless, and odorless (“Krypton”). It is located in group 18 and period 4 on the periodic table (Meadows). 36 protons are found within the nucleus of an atom of krypton, thus it has an atomic number of 36
(Meadows). Krypton’s name was derived from the Greek word kryptos meaning “hidden”, and the use of this word roots from the process that it took to discover krypton: it was “‘hidden’ in the residue after liquid air had nearly boiled away” (Weast and Astle B­22). With its historical background, special properties and multitude of uses, krypton is a chemical element that should not be overlooked.
In 1898, Sir William Ramsay and Morris William Travers of University College in
London, England first isolated the element krypton in pure form (Stewart). Ramsay’s previous discoveries of helium and argon are what inadvertently led to the discovery of krypton (Stewart).
Around the time of the discovery, Ramsay and Travers planned to extract a large volume of argon from the air, liquify the argon, and use distillation to discover a lighter element that would

fit between helium and argon (Stewart). Since the two chemists had little experience with liquid gases, they used liquid air to practice the procedure (Stewart). To begin, Ramsay and Travers evaporated the majority of the liquid air and left just 100ml remaining

    In this experiment, the molecular weight of a condensed vapor was found through a procedure using an unknown liquid. The flask before adding the unknown liquid in was full of air. After the beaker full of water started to boil the flask was examined until the unknown liquid was completely vaporized. At that exact point the flask contained all vapor. At the final weighing the flask contained condensed vapor and air. There is always a chance for error. Some sources of error could have come with completing this lab over an open water bath and some water vapor may have been in place. Also, too much vapor could have escaped and the experiment might not have been stopped quick…

    Uranium Saltss Lab Report

    Henri Becquerel became the first to discover radioactivity, gamma rays, and alpha and beta particles by studying uranium and other radioactive materials. Becquerel believed that Uranium phosphoresced, or absorbed energy from the sun and then emitted it in the form of light and radiation. He tested this by leaving Uranium salts, or potassium uranyl sulfate, in the sun for several hours and then leaving it, along with a coin, on a photographic plate. A photographic plate was used as an early photograph taking device. It was paper thin and darkened when it came into contact with light. When Becquerel left the plate with the Uranium salts on it he saw that ,once the plate was processed, it was blackened where the Uranium salts were placed. When Becquerel did this experiment again, it was a cloudy day, and the Uranium salts received little sunlight.…

    What is Krypton? Some might say it is the planet Superman is from, but it is actually a chemical element. Krypton is one of the rarest gases on Earth which makes it very expensive. It can also be found in Mars’s atmosphere, but only makes up 0.3 parts of a million. Krypton was discovered in 1898 by Morris Travers and Sir William Ramsey. It was named after the Greek word, kryptos, which means “hidden”.…
