why noble gas is unreactive?
147407
The atoms of noble gases already have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions. ... atoms of group 0 elements have complete outer shells (so they are unreactive)

Noble gas. 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 outermost electron shells (valence shells) are completely filled, so that they have little tendency to gain or lose electrons.

xenon and krypton(radioactive; can't say much) form most of the noble gas compounds so yeah in one way you can call them most reactive noble gases. Other noble gases take lots of effort (you can say) like temperature conditions and pressure to form compounds. How do noble gases exist in air?

The group 0 elements, the noble gases, are all unreactive non-metal gases. They show trends in their physical properties. Their uses depend on their inertness, low density and non-flammability.

All noble gases have full s and p outer electron shells (except helium, which has no p sublevel), and so do not form chemical compounds easily.

Question: The lightest noble gases, such as helium and neon, are completely inert - they do not form any chemical compounds whatsoever.

When elements react, their atoms complete their outer shells by losing, gaining, or sharing electrons . The atoms of noble gases already have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions.

The noble gases are happy with their completely filled valence shells. 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.

But Noble gases exist as monoatomic as their octet is complete therefore there is no other atom present which can pull the shared pair of electron in order to generate polarity hence all noble gases are non polar in nature.

Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.

1 Answer. They don't have values there because they aren't on the pauling scale of electronegativity, as they don't form any compounds with other elements. ... The other noble gases also can react with fluorine (As well as other elements), and make slightly more stable compounds.

Because noble gases' outer shells are full, they are extremely stable, tending not to form chemical bonds and having a small tendency to gain or lose electrons. ... Noble gas atoms, like the atoms in other groups, INCREASE steadily in atomic radius from one period to the next due to the INCREASING number of electrons.

Answer: An inert gas is one that does not undergo chemical reactions. Noble gases refers to the right most group of the periodic table composed of helium, neon, argon, krypton, xenon, and radon. As you might have seen as an example in class, some noble gases can form chemical compounds, such as XeF4.

The noble gases are in Group 18 (8A). They are helium, neon, argon, krypton, xenon, and radon. They were once called inert gases because they were thought to be completely inert—unable to form compounds. ... Because this configuration is extremely stable as well as symmetrical, the noble gases are very unreactive.

The number of shells depends on the element. ... We call these reactive elements, because these atoms really like to follow the buddy system and form bonds with other atoms. Noble gases, however, don't have this problem. Their outer shells are filled to the max, so they don't need to bond or react with any other atoms.

Noble Gases They were once called inert gases because they were thought to be completely inert—unable to form compounds. This is a reasonable belief because the noble gases have a complete octet, making them very stable and unlikely to gain or lose any electrons.

Ionization energies for all the noble gases are large, but they get LARGER as you go “up” the noble gas column, until you arrive at helium— the MOST unreactive of the unreactive noble gases. TL;DR: Helium.
