why noble gases are highly 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. Because of their high ionization energy and almost zero electron affinity, they were not expected to be reactive.

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.

Noble gases are placed in a separate group of the periodic table because they are inert elements. They are unreactive as their valence shells are completely filled with electrons.
844990
For a long time noble gases with completely filled electron shells were considered to be simple. Under normal conditions they are monoatomic inert gases. Their behavior, however, depends on such conditions as density, temperature and pressure. ... When cooled or compressed, noble gases become liquid or solid.

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.

All of the elements in Group Zero are noble gases. The list includes helium, neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). Don't think that, because these elements don't like to react, we don't use them.

Answer and Explanation: Argon is unreactive because it has the maximum number of electrons in its outer shell. According to the octet rule, most elements need to have 8...

Noble gases have highly stable fully filled electronic configuration which makes removal of electron extremely difficult. This accounts for the high ionisation enthalpy of noble gases.

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.

All noble gases are non metals. All the noble gases except radon occur in the atmosphere. All these are gases. They are chemically unreactive.
1429236
Noble gases like He, Ne, Kr, Xe and Rn are placed in a separate group because of the following reasons: - They are extremely unreactive. - They donot combine with any other element of the periodic table. - All the noble gas elements have zero valency and placed in zero group with similar chemical properties.

also have a full outer shell of 8 electrons, giving them great electronic stability and therefore chemical stability - very unreactive. The group 0 noble gases are the least reactive elements in the whole of the periodic table.

Noble gases are monoatomic because they have complete octet (apart from Helium, which has duet) , hence they are highly stable on their own and do not react with others to form compounds in standard temperature and pressure conditions.

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.

The Chemical Properties Noble gases are odorless, colorless, nonflammable, and monotonic gases that have low chemical reactivity. ... Although noble gases do not normally react with other elements to form compounds, there are some exceptions. Xe may form compounds with fluoride and oxide.

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.
