Except for He, all inert gases have an electronic configuration of ns2np6.
Inert gas or noble gas
The elements in Group 18 of the periodic table are known as the noble gases. These elements are also known as the inert gases
The members of group 18 in the modern periodic table are:
- Helium (He)
- Neon (Ne)
- Argon (Ar)
- Krypton (Kr)
- Xenon (Xe)
- Radon (Rn)
These gases are so-called due to the stability of these elements. This stability is due to the filled outermost shells of the elements. The noble gasses often do not react with many substances and have been historically called inert gases. They are called noble gases because they are so majestic that they do not react with anything in general.
- Neon, xenon, and krypton are used to produce different colour lights.
- Neon is used in discharge tubes.
- Helium balloons are used to check the weather of a particular region.
- A limited amount of argon is used in germanium and silicon crystals used in electric light bulbs, transistors, etc.
