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.

- Elements of the periodic table that are gases are just called gases. There is a whole group of elements in the table that are gases, and they're the inert gases or noble gases … . They comprise the elements of group 18 in the table.The inert gases are helium, neon, argon, krypton, xenon and radon.oble gases are elements that have all possible electron positions in the outer, or valence, shell filled. This makes them chemically non-reactive. They are found in group 18 … on the periodic table (far right edge) of elements (He, Ne, Ar, Kr, Xe, and Rn). 3 people found this useful.

- So the gases are in the non-metals section. An unreactive gas would most commonly be found in group 18 (last column) on the periodic table of elements. These are the noble gases, and have 8 electrons on their outer shell, so they are very stable. Since they are stable, they are unreactive.They rarely react with other chemicals.rgon is an element with atomic number 18. It has very low melting and boiling points. Argon, is a non-metal element and noble gas.

- Noble gases are colorless, odorless, tasteless, and nonflammable gases under standard conditions. In the periodic table, the noble gases are arranged according to their boiling point. Noble gases are widely used in different fields, from incandescent lighting to excimer lasers.

The Noble Gases The Noble Gases The elements of Group VIII of the Periodic Table are gases which have closed shells and are unreactive chemically. Helium, neon, argon and krypton are used in gas discharge decorative ligthing, called neon lights.

Noble gas The noble gases have weak interatomic force, and consequently have very low melting and boiling points. They are all monatomic gases under standard conditions, including the elements with larger atomic masses than many normally solid elements.

- At normal temperatures, krypton and the other elements in Group 18 are extremely unreactive. The reason is that, with the exception of helium, these elements' outer electron shells are filled to capacity with 8 electrons. This satisfies the octet rule, in which a full electron shell means maximum stability.

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. 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.

Inert gas The term inert gas is context-dependent because several of the noble gases can be made to react under certain conditions. Purified argon and nitrogen gases are most commonly used as inert gases due to their high natural abundance (78% N 2, 1% Ar in air) and low relative cost.rom Wikipedia, the free encyclopedia.

- The noble gases were previously known as inert gases because of their perceived lack of participation in any chemical reactions. The reason for this is that their outmost electron shells (valence shells) are completely filled, so that they have little tendency to acquire or lose electrons.

Helium Helium Helium is a colorless unreactive gas that is less dense that air. It belongs to the Noble gases which is the last group on the far right of the Periodic table. All of the Noble gases are chemically unreactive because they contain a complete number of electrons in the outer shell. Helium gas if often used in party balloons as it is lighter than air. Helium is also found in the sun and the stars where it is formed through a series of nuclear fusion reactions involving hydrogen.

- As noble gases are mostly stable in unimolecular form, they doesn't react with much other compounds, thus its actually becomes difficult to find one in surroundings. Noble gases are inert gases. They don't easily react and thus, their compounds are rare. Plus, they are trace elements.

What do the noble gases have in common ? 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) .

Noble gas For the first six periods of the periodic table, the noble gases are exactly the members of group 18 of the periodic table. It is possible that due to relativistic effects, the group 14 element flerovium exhibits some noble-gas-like properties, instead of the group 18 element ununoctium.

- Because of their uber-high stability, the noble gases are relatively unreactive. They have very high ionization energies and negligible electronegativities because they have no desire to gain or lose an electron.

Why do noble gases react? They have a full outer shell. A reaction happens for getting an outer shell (Taking and electrons) So if a noble gas has a full outer shell why does it sometimes react. AND Why is Xenon more reactive than Radon and 118 element even though they're further down the group and they all have an outer shell IT... show more They have a full outer shell.

Noble gas Helium is the most plentiful element in the universe except hydrogen. All the noble gases are present in Earth’s atmosphere and, except for helium and radon, their major commercial source is the air, from which they are obtained by liquefaction and fractional distillation.

Learn about Noble Gases The gases are elements, which share similar properties. These properties include being monoatomic, colorless, odorless, being able to conduct electricity, and having low chemical reactivity. Noble gases include Helium, Neon, Argon, Krypton, Xenon and Radon.

- The six noble gases are found in group 18 of the periodic table. They are Helium, Neon, Argon, Krypton, Xenon, and Radon in order of increasing atomic weight. These elements were considered to be inert gases, as they have a closed-shell configuration, until the 1960's, because their oxidation number of 0 prevents the noble gases from forming compounds readily. This was found to be incorrect in 1962 when Neil Bartlett succeeded in making the first complex xenon compound.

Xenon, Noble Gas Missing From Earth Atmosphere, May Be âHidingâ In Minerals The evidence is in every breath of air, but answers are harder to come by. Xenon, the second heaviest of the chemically inert noble gases, has gone missing. Our atmosphere contains far less xenon, relative to the lighter noble gases, than meteorites similiar to the rocky material that formed the Earth. The missing-xenon paradox is one of science’s great whodunits.

- The most characteristic property of the noble gases is their extremely low chemical reactivity as compared to other elements. The noble gases all have a full set of electrons in their outer shells, so they have little tendency to trade electrons with other elements to form compounds.

- Yes. Neon is a noble gas-a gas that will not react with any other element. The reason for this is that in an atom of neon, all the electron levels ('shells') are filled leav … ing no opportunity for it to react with other elements.   Other noble gases include Helium, argon, krypton, xenon and radon.

Noble gas The abundances of the noble gases decrease as their atomic numbers increase. Helium is the most plentiful element in the universe except hydrogen. All the noble gases are present in Earth’s atmosphere and, except for helium and radon, their major commercial source is the air, from which they are obtained by liquefaction and fractional distillation.

The Noble Gases At the top of the noble gases is little helium (He), with a shell that is full with only two electrons. The fact that their outer shells are full means they are quite happy and don't need to react with other elements. In fact, they rarely combine with other elements. That non-reactivity is why they are called inert.

Physical Science Textbook Argon and other noble gases are unreactive because their s and p orbitals are full. They do not lose or gain electrons and do not join with other elements to produce atoms. Describe why atoms of bromine, Br, are very reactive. To which family does bromine belong.
