What are noble gases?

Answer 1

Any elements in Group 18 are Noble Gases.

• Xenon
• Argon
• Radon
• Krypton
• Helium
• Neon

Answer 2

Oh so noble...

Noble gases are sometimes called inert gases, and they are the elements in Group 18 of the Periodic Table. They comprise the elements helium, neon, argon, krypton, xenon, and radioactive radon, which has no known stable isotopes.

These gases are found as single atoms as they do not like to interact with other atoms on the periodic table, hence the name inert. Their outer-most electrons shells (valence shells) are completely full with eight electrons (save helium with two), which "seals the deal" and defines the chemistry of these elements (see octet rule).

There are six noble gases:

• Helium (He)
• Neon (Ne)
• Argon (Ar)
• Krypton (Kr)
• Xenon (Xe)
• Radon (Ra)

Wikipedia has a brief article on the noble gases, and each one mentioned is done so with its name being a hyperlink to the Wikipedia post on that particular element. The link is in the "Related Links" section below.

All of these gases are found in air. They make up around 0.96% of the atmosphere. Noble gas compounds can be formed from nobel gases.

When the noble gases are used in cold cathode tubes to produce light, some noble gases have different colours. Since Radon is radioactive, it is usually not used for lightning.

Ununoctium (element 118) is probably the next noble gas after Radon. However it has a half life of 0.89 ms, after which it decays to Ununhexium (Element 116). This means its use is probably limited.
Noble gases: helium, neon, argon, krypton, xenon, radon

Champion 27:

Noble gases are the elements in Group 18 of the periodic table, which is the right most column. All of them have completely filled outer shells, so they are mostly inert and almost never react with other elements.

Answer 3

Noble gases are a group of elements on the periodic table that have complete outer electron shells, making them very stable and unlikely to form chemical bonds with other elements. The noble gases include helium, neon, argon, krypton, xenon, and radon. They are often used in applications like lighting, refrigeration, and medical imaging.

Answer 4

Noble gases are helium, neon, argon, krypton, xenon and radon.
