Noble gases have completely filled octet. It makes it difficult to get unstable.
All noble gases are stable except the last one, i.e. Radon(Rn)
Because noble gases are very unreactive only a small number of compounds is known: halides, oxides, salts, especially from xenon. Some compounds are unstable.
All the elemental gases except for the noble gases come in molecules that are unstable. The noble gases are all stable, they have the maximum number of valence electrons that their outer shell can hold.
The elements in group 18 are called the noble gases because they are very unreactive . The first noble gas compounds were made 50 years ago and so far unstable compounds have been made for all of them with the exception of Helium and Neon.
When alkali metals are mixed with noble gases, it can result in the formation of compounds known as intermetallic compounds. These compounds are usually unstable and highly reactive, making them useful for various applications in research and industry. The reaction between alkali metals and noble gases typically requires high energy input due to the low reactivity of noble gases.
When a noble gas loses an electron, it forms a positively charged ion. This ion is more stable compared to other elements because noble gases have a full outer electron shell, making them very unreactive. By losing an electron, the noble gas achieves a full valence shell, similar to the configuration of noble gases, thereby becoming more stable.
Radon is the name of the heaviest noble gas.
Noble gases are chemically inert.
it's not
There are no metals in noble gases.All are gases in noble gases.
All noble gases are gases in their standard state
They're all Noble gases.
