Xenon Xenon is element number 54 on the periodic table of the elements. It has a mass of roughly 131 atomic mass units. There are 77 neutrons and 54 protons in the nucleus of the atom. The symbol for xenon is Xe and it belongs to the family of elements called the noble gases. It is called a noble gas because the valance shell of one atom contains a full shell. Xenon is one of the most stable elements on the table. The 54 electrons are arranged, so that there are 2 in the 1st shell, 8 in the 2nd
periodic table and are chemical elements with similar properties. All of the noble gases have a full outer shell. None of them have color, odor, and all have very low chemical reactivity. There are six of them and they are Helium, neon, argon, krypton, xenon, and radon. Helium Helium has an atomic number of 2. It is has no color, no odor, or no taste. It is also an inert monatomic gas. It is the first of the noble gases on the periodic table. It’s melting and boiling points are the lowest among all elements
William Ramsay William Ramsay was born on the second of October, in the year 1852. William, and his parents, William and Catherine, lived in Glasgow, Scotland. William Ramsay performed his work in his native town, until 1870 when he went to Tübingen and earned his doctorate in 1872. When returned to Scotland later that year, he became an assistant chemist at the Anderson College in Glasgow. Eight years later, he was appointed principal and professor of chemistry at London University, which held
The emission spectrum of an element is the spectrum of frequencies in electromagnetic radiation emitted due to a specific atom's electrons, creating a transition from a high energy to a low energy state. There are many possible electron transitions for each different atom in which the transition has a specific energy difference. The collection of different transitions leads to different radiated wavelengths and in turn makes up an emission spectrum. Each element's emission spectrum is unique and
an author, and a short time businessman. Mr. William Ramsay is mostly known for his discovery of four of the noble gases. Ramsay also added the Noble Gases category to the Periodic Table of Elements. The four noble gases he discovered were Argon, Xenon, Neon, and Krypton. Ramsay furthered the discoveries of Helium and Radon, as well. In his later life, he was given many awards, such as the Nobel Prize for Chemistry, the Davy Medal, and was knighted. He was awarded the Nobel Prize in 1904. His later
my uses and ores, also the analytical methods based on me. I received the name krypton from the Greek word "hidden" because I was hiding for so long, undetected. I am from a rare group of gases called noble gases. The other noble gases are helium, xenon, neon, argon and radon. I was discovered in England in 1898 almost 100 years ago by Sir William Ramsey and Morris W. Travers. They found me in the less volatile part of inert-gas mixture left after oxygen had been chemically removed from a sample of
Recently, Jeff Bezos, the CEO of Amazon.com, said in an interview that he hopes to lay the foundation for a future of heavy industry in space. He suggests that within the coming centuries, portions of space will be zoned for heavy industry, while the Earth will become exclusively residential with some zones for light industry. There are great upsides to this concept, as solar power will not be hindered as it is on Earth, and there will not be an environmental impact on the home planet. Although,
Boiling point, similarly to melting point, depends on the strength of forces between the particles that make up the element. When a substance boils, most of the remaining attraction forces are broken, the particles can then move freely and farther apart. The stronger that the attraction force is the more energy that is needed to overcome them and increase the boiling point. Boiling points vary in a regular way or pattern depending on their position in the periodic table. The general periodic trend
the rarest of stable enert gases, xenon. It also tells why that in 1962 so many expirements were done involving this gas. Fisrt it defines the word gas, and talks about different types in about four pages. Thens he talks about how it is combined with flourine to form a poison. Death in the Labratory Here Asimov talks about how scientists have died due to poor lab conditions and other matters. He also tells you a few way to poison youself in a lab such as mixing xenon and flourine. He then goes off

Until recently people were stuck with large clumsy CRT (Cathode ray tube) devises within their everyday life, within the space of a decade after their move to television screens LCD’s (Liquid Crystal displays) and plasma screens have made CRT Displays obsolete. In this article I will explain in detail how the basic physics of LCD technology and plasma works and compare the two and decide which one is better for your needs. The wide range of applications for LCD displays are used for is impressive;
4.) Defense, how come you knew it was a maserati? - Hunter, Because they are my favorite kind of car. 5.) Prosecutor, you said that the car had xenon light bulbs that were purple, would you be able to know the same car if you saw it again? - Hunter, yes because those lights are very rare. 5.) Defense, you said that the purple lights where custom and didn't come with the car? - Hunter
gas produces a colored glow when excited by electricity passing through a glass tube in which the gas is confined. The name of the gas is Neon. Neon produces a reddish-orange color. Argon produces a faint purple. Krypton produces a ghostly white. Xenon produces a blue glow. No information exists on radon as
1 Organizing Veterinary Drugs For my final essay, I will be classifying different veterinary drugs we use daily into proper categories to help others learn and study each group to know which type of drug is necessary. The categories I will be explaining today are some of the more crucial drugs we use daily on animals and should be well known and categorized for optimal treatments. These include the following: 1. Analgesic opioids and anesthetics are common pain-relieving drugs and help us induce
“Everything I learned, I learned from the movies.” This was a quote by the old-time movie actress Audrey Hepburn. Usually as a child you would remember your favorite movie and are able to sing along to songs or quote your favorite character. The memories of that specific movie excite and bring back jovial thoughts. Most people have had this type of experience and that was all created possible by two brothers in Germany in the late 1800’s. November 1st, 1895 Max and Emil Skladanowsky invented the
Introduction: The instrument of fluorescence spectroscopy, also called as Fluorimetry or spectrofluorometry, is a type of electromagnetic spectroscopy that analyzes fluorescence from a specimen. It includes using a beam of light, commonly ultraviolet light, that excites the electrons in molecules of specific compounds and causes them to emit light; usually, but not needful, visible light. A finished technique is absorption spectroscopy. Both fluorescence and phosphorescence are examples of photoluminescence
plant located in southeast Pennsylvania. On March 28, 1979, a series of mechanical and human errors led to above-normal levels of radioactive gas being released into the air. Subsequently 400,000 gallons of water from a holding tank containing xenon-133 and xenon-135 was released into the Susquehanna River. (Davis 313) By the end of Thursday, March 29, detectable levels of increased radiation were measured over a four-county area. Plant officials estimated that 180 to 300 of the 36,000 fuel rods in the
In the early morning of April 26th, 1986, two explosions tore through the Chernobyl nuclear power plant leaving behind nothing but rubble, nuclear fallout, and the infamy of what will probably long be called the worst nuclear disaster in history (World Nuclear Association, 2013). The cities of Chernobyl and Pripyat remain ghost towns due to extremely high levels of radiation still present 28 years after the explosion. The undeniable environmental effects of the blast couple with the severe health
1. Johann Dobereiner • 1817-1829 Dobereiner began to cluster elements with similar properties into groups of three also known as triads. • Law of Triads- Began in 1817 when Dobereiner noticed the atomic weight of strontium, Sr, was midway between the weights of calcium and barium. These elements also had similar chemical properties. • In 1829 Dobereiner had discovered the halogen triad (chlorine, bromine and iodine) and an alkali metal triad (lithium, sodium and potassium). He proposed that
