noble gas Word History What makes a noble gas so noble? The noble gases are a group of six chemical elements, normally occurring in gaseous form, that do not react chemically with other elements or chemical compounds except very rarely. Helium and neon are two familiar examples.

noble A noble is a titled peer of the realm or an aristocrat. As an adjective, noble describes someone with high or elevated character, or who is impressive in appearance. From feudal times, we have known nobles as the heirs to thrones or as the holders of aristocratic title. British aristocracy, for example, produces many people of various noble titles, including dukes, earls, princes, kings, and queens. As various royal histories tell us, however, many of these nobles in title weren't quite so noble in character.

ARGON Photo by: concept w. Argon is a noble gas. The noble gases are the six elements in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how the chemical elements are related to each other. The noble gases are sometimes called inert gases because Group 18 (VIIIA) elements react with very few other elements.

The Noble Gases The Noble Gases We love the noble gases. Some scientists used to call them the inert gases. It didn't really work because there are a few other gases that are basically inert but not noble gases. Nitrogen (N 2) might be considered an inert gas, but it is not a noble gas. The noble gases are another family of elements, and all of them are located in the far right column of the periodic table.

Inert gas An inert gas is a gas which does not undergo chemical reactions under a set of given conditions. The noble gases often do not react with many substances.Inert gases are used generally to avoid unwanted chemical reactions degrading a sample.These undesirable chemical reactions are often oxidation and hydrolysis reactions with the oxygen and moisture in air.rom Wikipedia, the free encyclopedia.

The Noble Gases and Halogens The noble gases. This group contains helium, neon, krypton, xenon and radon. They are different to elements belonging to other groups due to their resistance to form compounds. The reason behind their unreactivity is their full outer shells that give stability to the atoms.

The Noble Gases The densities of the noble gases increase with increasing molecular mass. Helium is about one seventh the density of air and can be used in balloons and lighter-than-air craft. Xenon is about five times the density of air. Noble gases are used to advantage in environments where corrosion or damage from electrical discharges might occur if the environments were filled with air. One such use is in fluorescent light tubes.

Why are Noble Gases Unreactive Noble gases consist of atoms that have a full outer shell or valence shell. This means that they do not attract or require electrons from other atoms and therefore have no reason to react with them. Noble gases are very stable chemical elements.he Noble gases are a group of elements that possess many similar characteristics and properties. Noble gases as odorless, colorless, tasteless and non-flammable.

Why Are Noble Gases Not Reactive? Quick Answer.  Noble gases are unreactive because their outer electron shells are full and therefore in their most stable state. Normally, elements react with one another because they have incomplete electron shells. They lose, gain or share electrons in order to gain a more stable electron configuration.

What is noble gas notation? exists and is an alternate of . The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point onwards. The notation is shorter to write and makes it easier to identify elements.

Noble gas The noble gases make a group of chemical elements with similar properties. Under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity.The six noble gases that occur naturally are helium (He) , neon (Ne) , argon (Ar) , krypton (Kr) , xenon (Xe) , and the radioactive radon (Rn) .or instance, argon, krypton, and xenon form clathrates with hydroquinone, but helium and neon do not because they are too small or insufficiently polarizable to be retained. Neon, argon, krypton, and xenon also form clathrate hydrates, where the noble gas is trapped in ice.

- All of the Noble Gases are gases. The noble gases are all found in minute quantities in the atmosphere, and are isolated by fractional distillation of liquid air. Helium can be obtained from natural gas wells where it has accumulated as a result of radioactive decay. All these gases are monatomic.

Is there radioactive noble gas? If so, how is it used? Radon is a radioactive noble gas. It does not currently have any common industrial uses, but is sometimes used for hydrologic research on the interaction between groundwater and surface streams. Another noble gas, Krypton, has two uncommon naturally occuring radioisotopes, Kr-81 and Kr-85.
