What Does Neon Mean

Based on this, what can you infer about the reactivity of helium and neon? They are both noble gases so they are very resistant to a chemical reaction and don’t react to other elements.

Helium (Greek helios,"sun"), symbol He, inert, colorless, odorless gas element. In group 18 of the periodic table, helium is one of the noble gases. The atomic number of helium is 2.

As said before, Krypton is used in some types of photographic flashes, some fluorescent bulbs, and its mixtures are used in signs to give them a greenish-yellow glow. It was also once used in measurements and is used in lasers for lab use.

In our daily lives we use nickel an example is the green color on some glass. And of course on the five cents of America which is named Nickel uses a certain amount of nickel (25%). Nickel is also used in vegetable to make the reaction after it has been heated up. Nickel is also a shiny metal that can resist high temperatures. Nickel is a very interesting element on the periodic

Architects turn to zinc for its long, maintenance-free life and adaptability to various design styles ranging from traditional to modern. It is at the forefront of contemporary design. Zinc is also a major prospect to science and technology. Battery-powered laptops now can use a zinc-are battery, which provides more than 12 hours of usage on a single charge. That's almost ten times the runtime of the original battery. The battery can also give cars enough power to reach speeds up to 120 mph. A high-purity alloy of zinc and copper is used in water purification. Zinc is also the key ingredient in a new hi-tech tape that is helping law enforcement officials around the world conduct safer and more reliable undercover work. Consuming more than 40,000 tons annually, the toy market is also an important user of zinc.

Helium is very light so it is used in things such as balloons and zeppelins as is lighter than air so rises above it. Neon is also well known for helping make neon signs because when an electrical current is passed through it will glow an orangey red colour. Argon is used in lightbulbs as it does not react with the metal filament used in light bulbs as it is very inert. Xenon and Krypton are used in fluorescent light bulbs and also some photography equipment as it emits a very bright white light. Radon is used in chemotherapy to help cure cancer.

It is odorless and colorless, even though that fact may shock those who are more familiar with it in its iridescent form. According to the Jefferson Lab, the elements melting point is 24.56 K (-248.59°C or -415.46°F), and its boiling point is 27.07 K (-246.08°C or -410.94°F). Partially since the element is a nonmetal, it serves no conductivity purposes. Another factor that contributes to its lack of electrical conductivities is its density, which remains at .0008999 grams per cubic centimeter (Jefferson Lab Web). Furthermore, because of its usual state of matter, neon lacks ductility and malleable qualities, nor is it hard/solid. As far as conductivity is concerned, “Neon lights are made with filled glass or plastic tubes with Neon gas. As electricity passes through these tubes, electric discharge produces high-energy electrons that hit the neon atoms changing their energy state, as photon of light is emitted,” (UC Davis

Fluorocarbons are used in refrigeration and air conditioning. One chemical property of fluorine is that it creates a very strong bond with other atoms. Meaning that all of the products that are created with fluorine in them are much stronger than products created with different chemical compounds. Furthermore, it can be used to help molten metal flow. It is very useful in situations where molten metal must not stand still, but cannot move on its own. It allows a person to work with metal easier, because the metal is able to flow more smoothly.

Magnets are used for many different things! Magnets are used at different times or same times. Magnets could be used for businesses or to collect sharp object off of the ground. They are used to help people find things or hold things up. The first magnets were not invented, but rather were found from a naturally occurring mineral called magnetite. Traditionally, the ancient Greeks were the first discoverers of magnetite. (William Orem) (posted March 7, 2013) site:http://indianapublicmedia.org/amomentofscience/history-magnetite/

Until World War II, no commercial product of fluorine was being produced. Although, the nuclear bomb project and energy applications made it necessary to begin producing it in large quantities. Chlorofluorocarbons (CFCs) were used in appliances such as refrigerants, air conditioning units, and freezers. They since been banned because of their contribution to ozone depletion.

n = 3 to n = 2 is called Balmer-alpha or H-alpha, and is visible in the red part of the electromagnetic spectrum. This is the easiest way for astronomers to trace the ionized hydrogen content of gas clouds. Since it takes nearly as much energy to excite the hydrogen atoms electron from n = 1 to n = 3 as it does to ionize the hydrogen atom, the probability of the electron being excited to n = 3 without being removed from the atom is very small. Instead, after being ionized, the electron and proton recombine to form a new hydrogen atom. In the new atom, the electron may begin in any energy level,

It’s deadly to breath in pure oxygen so divers mix it with helium in order to breath underwater!! Depending on how low the diver will dive, the helium/oxygen ratio needs to be accurate in order to dive safely. One of the greatest uses of helium is for cryogenics. When helium is liquefied it is one of the coldest substances known to man. Helium boils at the temperature of 4 Kelvin (452 degrees Fahrenheit). It is commonly used in magnets for MRIs and nuclear magnetic resonance spectroscopy. These magnets are made with superconducting wires that allow electric current to circulate forever as long as they are cold enough. Helium enforces that and makes the magnet running forever without any loss of resistance over time. Liquid helium is used any time someone needs extremely cold temperatures. Helium is also well know for the use of weather balloons. They use really big helium filled balloons that takes the balloon up almost into space with the use of helium. They take the balloon close to space to study atmospheric conditions with great detail. This is why scientists can predict what the weather will be like! Another really good use of helium is for welding. When arc welding, an electric arc has to be created to heat the materials up that are being worked on. It will rise to very high temperatures and it will melt. At these temperatures an inert gas is needed to protect the materials from

To begin with, germanium is used in the manufacture of wide-angle camera lenses. The element gives special properties to the glass. Since, germanium has traits that are similar to silicon and tin, the semiconductor industry uses germanium is used to make transistors for use in electronic devices. Germanium is also used to create alloys and as a phosphor in fluorescent lamps. In other words, germanium is used to make camera lenses for electronic

Two of its earliest applications were as part of smoke and fire detection systems and camera light meters. Because cadmium sulphide cells are relatively inexpensive and widely available, LDRs are used in electronic devices that need light detection capability, such as security alarms, street lamps, and clock radios.
