why are noble gases are 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)

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.

The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.

Argon is the third of the noble gases or inert gases. It is very non-reactive. So much so, that it forms compounds with virtually no other elements. ... That is why it does not easily combine with other elements.

Noble metals already have there outermost electron shells completely filled. So they do not need to partake in reactions. Hence they're their unreactivity. ... However, noble metals already have a full shell of valence electrons so there is no need for them to react.

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.

Chemical Properties of Noble Gases Noble gases are the least reactive of all known elements. That's because with eight valence electrons, their outer energy levels are full. The only exception is helium, which has just two electrons.

Nitrogen, the unreactive gas On the other hand, nitrogen is not a noble gas. Two nitrogen atoms make up the nitrogen molecule (N2), so it has no free electrons like Argon and thus the same properties of a noble gas under nearly all uses. Indeed, nitrogen, which makes up 79.1% of our atmosphere, is very unreactive.

Inert gases by definition are nonreactive and monatomic, (single atom), because there is no need to form bonds in order to satisfy an unbalanced charge state. ... While the noble gases are most commonly found as monatomic elements, they can form compounds with other elements.
468485
The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons. Although noble gases do not normally react with other elements to form compounds, there are some exceptions.

Helium is slightly different than the other noble gas elements. It only has two electrons in its outer shell so its valence electron configuration is 1s2. ... The noble gases are happy with their completely filled valence shells. Because of their uber-high stability, the noble gases are relatively 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.

Noble gases have large positive electron gain enthalpy. This is because the extra electron is placed in the next higher principal quantum energy levels. Thus, a highly unstable electronic configuration is produced.
521673
The electron configuration of noble gases shows that they are stable elements. ... In other words, they have a full valence shell and do not readily form compounds with other elements (do not react).

The noble gases of Group 8A (He, Ne, Ar, Kr, Xe, and Rn) are all gases at room temperature (as the name of the group implies); since they are all unreactive, monatomic elements, their boiling points are extremely low.

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.

Elements in group 18 of the periodic table – the “noble gases”, tend not to form ions due to the arrangement of their electrons which makes them generally unreactive.
