why are noble gases less reactive?
151925
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 1 and 7 elements have incomplete outer shells (so they are reactive )

The main properties of the noble gases include: they have low densities. they are inert, so they are not flammable.

The “Noble Gases” are Helium, Neon, Argon, Krypton, Xenon, and Radon. ... They are all gases because in their natural state they have a complete octet of outer electrons and don't need another atom to be complete. They are the only atoms which do not combine with themselves like oxygen is O2 and fluorine is F2.

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.

Under ordinary conditions, noble gases are inert and don't form compounds, but when ionized or under pressure, they will sometimes working into the matrix of another molecule or combine with highly reactive ions.

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)

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.

The science. The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don't react with anything. For this reason they are also known as inert gases.

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. ... As a result, noble gases cannot become more stable by reacting with other elements and gaining or losing valence electrons.

Question: The lightest noble gases, such as helium and neon, are completely inert - they do not form any chemical compounds whatsoever.
1010738
All the noble gas elements have zero valency and placed in zero group with similar chemical properties. ... The noble gases like helium,neon. argon, krypton and xenon are placed in a separate group because these are inert ( un-reactive ) and present in very low concentration in the atmosphere.

All of the noble gases have full outer electronic shells and thus are not reactive. However the larger the atomic weight of the Noble Gas the farther away are the electrons in the outer shell. ... As xenon lies close to the bottom, it is highly reactive as compared to other noble gases. And hence,it easily form compounds.

It was initially believed that the noble gases could not form compounds due to their full valence shell of electrons that rendered them very chemically stable and 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 Chemical Properties 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.

Octet Rule. The noble gases are unreactive because of their electron configurations. The noble gas neon has the electron configuration of 1 s 2 2 s 2 2 p 6 . It has a full outer shell and cannot incorporate any more electrons into the valence shell.

Noble gases are fairly non-reactive and have low boiling points. The elements classed as Noble Gases have the following properties in common: They are non-metals. Very un-reactive gases.

Noble gases are very stable chemicals that do not react easily with other chemicals and are not flammable. ... These gases are not very toxic but they can be harmful in large amounts. Noble gases are asphyxiants. Asphyxiant gases replace oxygen in the air so there is less of it to breathe.
