Neon is not reactive and doesn't cause any harm. Neon isn't that useful becuase there aren't any known compounds that involve neon yet. When compunds are found that involve neon it may turn into a villain but so far it's one of the good guys Discovered by: sir william ramsy & Morris m. travers When: 1898 Where: Europe Where on earth is it found naturally: 0.0018% of the earths atmoshpere isotopes fo neon neon signs in advertising Neon is also used to make high voltage indicators and switching gear, lightning arresters, diving equipment and laser Superhero vs Super Villain Safety Precautions Period: 2 group: 18 Key Interesting Facts Uses and Impact on STSE

When was it discovered? When? Neon was discovered in 1898. Who Discovered It? Who? Neon was discovered by Scottish chemist, Sir William Ramsey and English chemist, Morris Travers. Why is it named that? Why? Neon's name comes from the greek word "neos", meaning "new" Neon can be found in 2 places, the Earth's crust and the Earth's atmosphere. It is considered a very rare element and it can also be produced from a process called distillation. Where is it typically found in the world? Where? Physical Properties Physical Properties What does Neon look like: Neon, under its normal conditions is a very light, inert gas. When it glows it gives off a reddish-orange color. Metal, Metalloid, or Non metal? Metal Non-Metal Metalloid Neon is a non metal. Melting & Boiling Point Melting & Boiling Point Melting Point: -248. 57 C Boiling Point: -246.0 C CONVERSION Solid, Liquid, Gas? This gas is colorless and odorless Neon is a monatomic gas. Density & Hardness Density & Hardness Density: 0.0009 g/cm cubed Hardness: Neon is not hard because it is a gas. 3 uses for this element: Brightly lit signs Television tubes Refrigerant when in liquid form How is it beneficial? Neon produces a very vibrant light that has been used for many signs. Such as when a store needs to let people know if they're open or closed they purchase those signs. I think it is very beneficial to our society. Names for 3 common compounds : Fluorine, NeAr, NeH Is my element important: Yes, I think Neon is one of the most important elements. Neon is also used as a refrigerant which is a chemical used for air conditioning. I think every human needs an air conditioning and Neon is a component of allowing us to have it. Chemical Properties and Uses
Transcript: When energy hits electrons, the elctron will jump levels appropriate to the amount of energy absorbed. This sends the electron in an excited state and offsets the electron configuration. When the electron leaves it's excited state, it will lower and emit the energy it absorbed, normally emiting photons which result in colour. Why do electrons jump between levels and what happens when it goes back? The larger the jump, the more energy it absorbs and emits, the smaller the wavelength. In other words, a smaller jump will emit infrared, a medium jump makes visible colour, and a big jump makes ultraviolet photons. The length of jump for infrared light, visible light, and ultraviolet light. Wavelength(λ)-->Frequency(v) Frequency is the number of wavelengths that occur in a period of time. c=λv Wavelength(λ)-->Energy(E) The smaller the wavelength the more energy it took to make it. v=c/λ-->E=hv Frequency(v)-->Energy(E) The higher the frequency the higher the amount of energy used is.

However there is no known use for the compounds yet. Neon was discovered in 1898 in London, England, by Sir William Ramsey by working with liquid air. Today it can be used to glow orange in a linear tube, to create neon lights, can be used for refrigeration purposes, and being the most intense on standard electrical currents. Atomic Symbol [Ne] The history of Neon Neon is non-toxic and has no biological role yet. Neon has a boiling point of about -415 degrees farenheit and a melting point of -410 degrees farenheit Neon is the 4th most abundant gas in the universe, but there is only 0.0018% in Earth's atmosphere Neon has a cubic crystal structure Neon may glow orange in linear tube, but it is in fact collorless and odorless. Compounds Containing Neon I've got a [Ne]at element for you to learn about! Credits Neon! Basic facts about Neon atomic number = 10 VE = 8 add logo here

However it can become an asphyxiant in small places. The lack of oxygen would cause the victim to suffocate. Sir William Ramsay and Morris Travers discovered it in 1898. The element was discovered through work on liquid air. The name comes from the Greek word neos, meaning new. Uses of Neon Krypton Physical and Chemical Properties Xenon Neon is a colorless, odorless, tasteless gas. Its boiling point is -245.92°C and its melting point is -248.6°C. Its density is 0.89994 grams per liter. Neon is chemically inactive, meaning its been impossible to make neon react with any other element or compound. Isotopes are atom modifications of the same element that difference by different atomic mass value. Neon has 3 isotopes, Ne-20, Ne-21 and Ne-22. Ne-22 is used in nuclear research.Ne-20 and Ne-21 isotopes are used in lasers and electronics industry.Six other unstable isotopes are known for neon. By: Manuela Reyes Neon belongs to the noble gases family. It is located in Group 18 of the periodic table with all the other noble gases. This gases usually don't interact with other elements or compound. All of this gases are found in air and they compose about 0.96% of it the atmosphere. History

Cooled a small amount of the atmosphere till it turned into liquid What does it look like? The element itself at room temperature is actually colorless, odorless, and tasteless But when it’s heated, it becomes one of the most intense lights, giving off a bright yellow, a dramatic red, and a faint violet and green When-1898 Where-London, England With the help of the NEON (cc) image by nuonsolarteam on Flickr Spectrometer There are reports of Neon forming an unstable hydrate How was it discovered? Scottish Chemist: William Ramsay Neon is considered to be INERT - no true compounds of Neon exist... Purpose - Advertisement is what mainly uses neon - (signs, lamps, etc) ^ attracting and entertaining people all over English chemist: Morris Travers The Little Things Atomic # - 10 Atomic Mass - 20.12 Valence # - 8 Melting point- -248.67 C Boiling Point- -246.048 C Period 2 and Group 18 A Noble Gas Density- .899 g/liter Uses Now - High-voltage indicators (used to determine amount of volts, etc) - Lightning arrestors (used to protect other equipment from lighting and switching surges) - Vacuum Tubes Using “spectroscopy” they were able to see tiny amounts of gas by analyzing the light of an element when the element was heated. The lines of light appeared and were colors of bright yellow, a faint violet and green, and a dramatic red NEON 3 Stable Isotopes Ne-22 – used for production of Na- 22Ne-21 – used in Masers to study quantum physicsNe-20 – used for production of F - 18 nitrogen, oxygen, and argon make up 99.966% of the air on Earth Where is it found? - Earth’s atmosphere and Earth’s crust Abundance - Neon is the fourth most abundant in the universe and the fifth most abundant in the earth's atomosphere History And thus Neon was born Old Uses - Neon was used for lighting Moore Tubes - George Claude’s “Air Liquide” company produced the first two neon light signs - By 1920’s neon lighting became extremely popular and changed the advertising world - used for signs in hotels, restaurants, etc - the element also helped with the discovery of isotopes of stable atoms
