What is noble gas?

Answer 1

any gas which has a stable electronic configuration...a completely filled outer orbitals.

Answer 2

A noble gas is one whose outermost shell is completely filled.
Ex :- Neon atomic no=10

electronic configuration is 1s2 2s2 2p6

Noble gases are found in the18th group of the periodic table.

Answer 3

Noble gases are in Group 0 or 8 of the Periodic Table. Egs are Helium, Neon, Argon, Xenon, Krypton.

They have 8 valence electrons on their outermost shell,except for helium, which has 2 valence electrons on the outermost 1s orbital.

They do form compounds too, eg. XeF4, XeF2, XeF6, XeO3,
XeO6 4-

The noble gases are minor constituents of the atmosphere.

Answer 4

The noble gases are the chemical elements in group 18 (old-style Group 0) of the periodic table. This chemical series contains helium, neon, argon, krypton, xenon and radon. The noble gases were previously referred to as inert gases, but this term is not strictly accurate because several of them do take part in chemical reactions. Another older term was rare gases, although in fact they form a considerable part (0.93% by volume, 1.29% by mass) of the Earth's atmosphere.

The noble gases are the chemical elements in group 18 (old-style Group 0) of the periodic table. This chemical series contains helium, neon, argon, krypton, xenon, and radon. The noble gases were previously referred to as inert gases, but this term is not strictly accurate because several of them do take part in chemical reactions. Another older term was rare gases, although in fact argon forms a considerable part (0.93% by volume, 1.29% by mass) of the Earth's atmosphere.

The name 'noble gases' is an allusion to the similarly unreactive Noble metals, so called due to their preciousness, resistance to corrosion and long association with the aristocracy. One of the most commonly encountered uses of the noble gases in everyday life is in lighting. Argon is often used as a suitable safe and inert atmosphere for the inside of filament light bulbs, and is also used as an inert atmosphere in the synthesis of air and moisture sensitive compounds (as an alternative for nitrogen). Some of the noble gases glow distinctive colours when used inside lighting tubes (neon lights). Helium, due to its unreactivity (compared to flammable hydrogen) and lightness, is often used in blimps and balloons.

Answer 6

The noble gases are the chemical elements in group 18 (old-style Group 0) of the periodic table.
For example : helium, neon, argon, krypton, xenon, and radon.
Theyre also called inert gases .. They do not chemically react under normal conditions ..
And also they form 0.93% (by volume) of the earth's atmosphere ..

Answer 7

In the mordern periodic table...the 18th group elements are known as noble elements and and when they are in gaseous state they are known as noble gases...

The word noble actually relates to their property that they don't react with any element, as they have fully filled orbitals and there is no scope for further fillin !!

Thats all...hope u got the point...okay so eg. is Argon, xenon..etc

Answer 8

Noble Gas are the un-reactive gases (non-metallic elements) present in nature. These gases don't react with other elements freely. The noble gases are Helium (He), Neon (Ne), Argon (Ar), Xenon (Xe), Krypton (Kr) and Radon (Rn).

Answer 9

Noble gas are colourless,odourless, and occur in tiny amounts in the atmosphere.They have stable electronic configuration , with no unpaired electrons to share ,make them extremely unreactive- hence "noble" or "inert" gas. HELIUM, NEON, ARGON, KRYPTON,XENON, and RADON.

Answer 10

Noble gases are the 8 group in the periodic table. they have satble electronic configuration and so are unreactive. Mainly they include Neon, Xeon or Xenon, Krypton, Helium etc

Answer 11

All the gases that do not react or combine with another substance chemically in any condition are called noble gases.
