Noble gases are those which are colorless, odorless, tasteless, and non-flammable. Their name comes from the fact that they were initially believed to never bond with other atoms which was later disproved.

∙ 10y agoA noble gas is an element found in group 18 of the Periodic Table, characterized by having a complete outer electron shell that makes them stable and non-reactive with other elements. These gases include helium, neon, argon, krypton, xenon, and radon. They are often used in lighting, welding, and artificial atmospheres.
The noble gas configuration of mercury (Hg) is [Xe] 4f^14 5d^10 6s^2, which means it has the same electron configuration as xenon plus two additional electrons in the 6s orbital.
An atom in a ground state with 8 valence electrons is likely to be an oxygen atom. Oxygen has 6 electrons in the outermost shell, also known as the valence shell, along with 2 electrons in the inner shell. This configuration allows oxygen to easily form chemical bonds with other atoms to achieve a more stable electron configuration.
Yes, they have stable electron configuration i.e, their outer most shell has all its valence electrons filled.Some famous noble gases areHelium (He)Neon (Ne),Argon (Ar),Krypton (Kr),Xenon (Xe),and the radioactive Radon (Rn).

Tear gas contains chemicals such as chloroacetophenone or CS gas. Laughing gas is nitrous oxide.

The main noble gas in Earth's atmosphere is argon, which makes up about 0.93% of the atmosphere.
At normal pressure, any temperature above 165.051 K.
