What I have to present to you will not only amaze you, it will thrill you. This noble gas is the second lightest known noble gas on the planet, after helium. It is present in the atmosphere to the degree of one part per 65,000 parts of air. The Atomic number of the noble gas is 10 with an atomic weight of about 20.18. It is in the 18th column and the 2nd row on the periodic table of elements, and it can be used in many lights and signs for your company. I think that neon on will be an incredible value to the modern world and can be used for wonders of things.
Neon is the second lightest noble gas in the atmosphere and is a colorless, odorless, tasteless chemical element. Neon however, a very inert element, is said to form a compound with fluorine, but it is still very questionable if true compounds exist. Evidence is increasing in favor of their existence. This element is known to form an unstable hydrate. Also, the discharge of neon is the most intense of the rare gases at ordinary currents and voltages. Neon contains a melting point of -248.67°C and a boiling point of -246.048°C. With all of these properties of neon, you are able to create beautifully colored, and vibrant lights, as well as eye-popping sings to help promote your manufacturing business and bring more people, like me, to either purchase or create new products. Another product you can make off of neon is tiny tubes that can be made meters in length, that can be bent, and a colorful light is discharged.
The positioning of Neon on the periodic table of elements is the 18th column, 2nd row. On the periodic table, neon is known as Ne and has an Atomic Number of 10, and an Atomic Weight of about 20.18. Neon contains both 10 neutrons and 10 protons with a match of 10 electrons. Here (point to bored) I have drawn an example of Neon’s Bohr-Rutherford model. As u can see, the solid circle I have drawn to represent the nucleus, has 10 protons as well as 10 neutrons. I have also drawn 2 orbits around.
In nature, the chemical element neon is found in its gaseous state only. It is found in the Earth's atmosphere in trace amounts. In fact, commercially, neon is obtained from air. For industrial uses, it is produced by fractional distillation of liquid air through the cryogenic method. Besides, volcanic gases are rich in neon. Even though it is quite a rare element on the Earth, it is abundantly found in the universe. It comes fifth among the most abundant elements of the universe. Its less availability on our planet is owing to the fact that it is light in weight and is chemically inert.
Discovery of Element Neon
The credit for the discovery of this element goes to Scottish chemist Sir William Ramsay and English chemist Morris W. Travers. The duo also discovered two other noble gases namely, krypton and xenon. They discovered neon in London in the year 1898. During the experiment, Ramsay cooled down a sample of air to such a low temperature that it became liquid. This liquid air was then boiled, and the gases thus released; were collected. Apart from other atmospheric gases like oxygen, nitrogen, argon and krypton; neon was also found in the collection of gases and was characterized by its bright red color emitted by the electrically activated neon atoms. The name of this element is derived from the Greek word neon which means 'new one'.
Properties of Neon
In chemistry, neon is represented with chemical symbol Ne. In periodic table, it is placed in group 18 along with other five noble gases. In this group, it is placed just below helium. It is also a member of p-block of the periodic table and it is the first noble gas of the block.
Neon is one of the lightest of all the noble gases, and is a colorless, odorless, and tasteless substance. Under low pressure or in vacuum condition, if electric current is passed through neon gas, it emits a typical reddish orange light that we see in advertising signs. Liquid range (the temperature at which a gas remains in liquid form) of neon is the narrowest of all elements. Its refrigerating capacity is about forty times more than that of liquid helium and three times more than liquid hydrogen.
The atomic number of neon is 10 and its atomic mass is 20.18. There are three stable isotopes of neon, namely: neon-20, neon-21, and neon-22. The atomic number of neon clearly specifies that it does not have any free electrons in its electronic shells. Therefore, under normal conditions, it is a monatomic element. In other words, a neon molecule consists of one single atom only.
Neon is considered to be a chemically inert substance. Its chemical reactivity is the least among all the noble gases. It can be said that it is the most inactive element. So far, there are no known compounds of neon; and even neutral compounds are not available. However, presence of some ions like Ne +. (HeNe + ), (NeH) +. etc. have been found during studies of optical and mass spectrometry. Besides, there are some unconfirmed reports about existence of an unstable hydrate of neon.
The element neon is used in many different ways. It has usage in vacuum tubes, wave meter tubes, television tubes, high-voltage indicators, and lightning arrestors. Neon is also used along with helium for the purpose of making gas lasers. It has a distinguishing reddish-orange color glow when it is used in lamps or discharge tubes. Commonly used neon lights have two different varieties. One is the glow-discharge lamps which are small in size and can operate at low voltage. These lamps are popularly used in circuit-testing equipment and power-on indicators. The other one can operate at a very high voltage and is most widely used in advertising signs.
Another important usage of this element, is as a cryogenic refrigerant. Commercially, it is a more popular refrigerant, as it is less expensive as compared to helium. The triple point temperature of neon (the temperature at which all three phases, solid, liquid, and gaseous form of neon co-exist) has a defining fixed point, and is employed in the International Temperature Scale of 1990.
Since neon is nontoxic in nature, no precautions are needed for handling this chemical element. The only problem with neon is that its liquefied form is highly expensive and is very difficult to obtain it in small quantities for use in the laboratory tests.

Did you know that neon is a Greek word that means "new"? Neon is the element that I am most interested in. I chose to do neon because I found out what many uses it has in our daily life. Neon is the element that allows you to watch TV. Without neon we would never see the cool flashing signs outside of diners and bars. In my essay I am going to tell you about neon and its many uses.
First, I'm going to tell you about the history and uses of neon. Neon was discovered by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, shortly after their discovery of the element krypton in 1898. Neon is one of the most amusing elements used today. Neon mixed with some other elements can make a bright light in an enclosed tube. This is mostly used in advertising signs (figure A) (A blue or green coloration in the discharge can be done by adding a little mercury to the neon in the discharge tube), but when used in a different mixture of molecules it can make the figures on your TV (figure B). Neon is also used in
High voltage indicators (figure C) and neon-helium laser pointers (figure D).
Now I?m going to give you the chemical breakdown of neon. Neon?s atomic number is #10. Neon has 10 protons, 10 neutrons, and 10 electrons. It belongs to the Noble Gas section of the periodic table. Its atomic mass is 20.1797. All the noble gases have the maximum number of electrons possible in their outer shell making them stable and unable to bond with other elements. All of the gases have eight electrons on their outer shell except for Helium has two. Neon is found in the atmosphere. Neon is 0.002% of the atmosphere. Also, stars produce neon during the later stages of nuclear fusion.
All there is to talk about neon now is about how it integrates into our life. To show you the integration in our society I will demonstrate a situation in which neon comes into play. Imagine walking around in Las Vegas with your friends looking to have a good time before your business meeting the next day. You look up and see giant signs that flash and move around advertising casinos and restaurants. Those signs are discharge tubes holding the active ingredients of our friend neon and his buddy mercury. You decide to walk into the casino with the biggest, coolest sign that says "MGM". You walk into the casino wondering what to do first, so you walk over to the nearest craps table. You play craps for a couple hours and decide to cash in and go out to eat with all the money you won. You walk into a sports bar to get a drink and you notice a TV with the Lakers game on. You look up at the TV and notice they are losing 84 to 36. The television has a tube in it that holds neon to project things onto the glass screen you see, without neon you wouldn't be able to watch any of your favorite shows. When you are finished eating your friends ask if you want to go

Neon is the second-lightest noble gas, its colour is reddish-orange in a vacuum discharge tube and in neon lamps. The the refrigerating capacity of helium is over 40 times the one of liquid helium and three times that of liquid hydrogen (on a per unit volume basis). It is a less expensive refrigerant than helium in most applications.
Even though neon is for most practical purposes an inert element, it can form an exotic compound with fluorine in the laboratory. It is not known for certain if this or any neon compound exists naturally but some evidence suggests that this may be true. The ions, Ne +. (NeAr ) +. (NeH ) +. and (He Ne + ) are have also been observed from optical and mass spectrometric research. In addition, neon forms an unstable hydrate.Applications
The reddish-orange color emitted in neon lights is widely used to make advertising signs. Neon is also used generically for these types of lights when in reality many other gases are used to produce different colors of light. Other uses of neon include high-voltage indicators, lightning arrestors, wave meter tubes and television tubes. Neon and helium are used to make a type of gas laser.
Liquefied neon is commercially used as an economical cryogenic refrigerant.
Neon in the environmentAlthough neon is the forth most abundant element in the universe, only 0.0018% in volume of the earth's atmosphere is neon.
Neon is usually found in the form of a gas with molecules consisting of a single Neon atom. Neon is a rare gas that is found in the Earth's atmosphere at 1 part in 65,000.
Routes of exposure: The substance can be absorbed into the body by inhalation.
Inhalation risk: On loss of containment this liquid evaporates very quickly causing supersaturation of the air with serious risk of suffocation when in confined areas.
Effects of exposure: Inhalation: Simple asphyxiant. Skin: On contact with liquid: frostbite. Eyes: On contact with liquid: frostbite.
Inhalation: This gas is inert and is classified as a simple asphyxiant. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death. Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue. At low oxygen concentrations, unconsciousness and death may occur in seconds without warning.
The effect of simple asphyxiant gases is proportional to the extent to which they diminish the amount (partial pressure) of oxygen in the air that is breathed. The oxygen may be diminished to 75% of it's normal percentage in air before appreciable symptoms develop. This in turn requires the presence of a simple asphyxiant in a concentration of 33% in the mixture of air and gas. When the simple asphyxiant reaches a concentration of 50%, marked symptoms can be produced. A concentration of 75% is fatal in a matter of minutes.
Symptoms: The first symptoms produced by a simple asphyxiant are rapid respirations and air hunger. Mental alertness is diminished and muscular coordination is impaired. Later judgment becomes faulty and all sensations are depressed. Emotional instability often results and fatigue occurs rapidly. As the asphyxia progresses, there may be nausea and vomiting, prostration and loss of consciousness, and finally convulsions, deep coma and death.
Neon is a rare atmospheric gas and as such is non-toxic and chemically inert. Neon poses no threat to the environment, and can have no impact at all because it's chemically unreactive and forms no compounds.
No known ecological damage caused by this element.
