why are noble gases noble?
27703
Noble gas. The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.

All noble gases are non metals. All the noble gases except radon occur in the atmosphere. All these are gases. They are chemically unreactive.

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.

The noble gases are the elements in group 0 of the periodic table. They all have a full outer electron she'll. This is the most stable arrangement of electrons which other elements only achieve by making ions or sharing electrons in covalent bonds. This is why the noble gases are inert, compared with other elements.

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. ... 0.0018% Neon.

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. Their properties are different when compared to all the other elements.
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 )

Noble gases like helium (He), Neon (Ne), and Argon (Ar) are chemically inert and are present in atmosphere in extremely low concentrations. Thus owing to their similar inert behaviour and similar electronic configuration, they are justified to be placed in a separate group.

You're right that the noble gases have high ionization energy. However, they only have the highest ionization energy in their period because they are the most stable elements. Moving down the noble gases group, the ionization energy decreases.

Other characteristics of the noble gases are that they all conduct electricity, fluoresce, are odorless and colorless, and are used in many conditions when a stable element is needed to maintain a safe and constant environment. This chemical series contains helium, neon, argon, krypton, xenon, and radon.

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.

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.

The noble gases are used to form inert atmospheres, typically for arc welding, to protect specimens, and to deter chemical reactions. The elements are used in lamps, such as neon lights and krypton headlamps, and in lasers. Helium is used in balloons, for deep-sea diving air tanks, and to cool superconducting magnets.

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.
