Noble Gas Notation and Noble Gas Electron Configuration

At the end of the article, you will able to write Noble Gas Notation and Noble Gas Electron Configuration. We also recommend reading this Inert Gas link. Let’s start discussing one by one.

Noble Gas Notation and Noble Gas Electron ConfigurationThe noble gas (group 18- also called Inert gas Group) elements have the Outermost configuration of Inert Gas is ns2, np6. Therefore, they have a little or no tendency to react with other elements to form compounds.

Noble Gas Notation

While writing the notation make sure that you have written with the nearest inert gas element.

Element Configuration Nearest Noble Gas Notation
Na (Sodium) 1s2,2s2,2p6,3s1 [Ne]=1s2,2s2,2p6 [Ne]10,3s1
Mg (Magnesium) 1s2,2s2,2p6,3s2 [Ne]=1s2,2s2,2p6 [Ne]10,3s2
 Al (Aluminum)  1s2,2s2,2p6,3s2,3p1  [Ne]=1s2,2s2,2p6  [Ne]10,3s2,3p1
 K (Potassium)  1s2,2s2,2p6,3s2,3p6,4s1  [Ar]=1s2,2s2,2p6,3s2,3p6  [Ar]18,4s1

 Noble Gas Electron Configuration

Atomic Number  Element Electronic Configuration
2 Helium 1s2
10 Neon [He] 2s2p6
18 Argon [Ne]3s23p6
36 Krypton [Ar]3d104s24p6
54 Xenon [Kr]4d105s25p6
86 Randon [Xe]4f145d106s26p6

From the above table it is obvious that all of them, except helium, have the highly stable s2p(octet) configuration in the outer (valence) shell. Helium has the stable s2 (duplet) configuration. Because of this configuration, they are chemically unreactive and possess zero valencies.

Heaviest Noble Gas

Randon is one of the heaviest among noble (Inert) gases. Its atomic number is 86. The total 86 electrons complete the outermost octet so as to achieve the maximum stability.

Lightest Noble Gas

Helium is the lightest among Inert gases. Most helium was formed during the Big Bang.  It is the second lightest element in the periodic table. Its configuration is 1s2

Radioactive Noble Gas

Radon is a chemical radioactive element with symbol Rn. It is a radioactive, colorless, odorless, tasteless gas. It is obtained when radium disintegrate.

Noble Gas Colors

Element Colors
Helium Pale yellow to orange
Neon Reddish-orange
Argon Purple to pale lavender blue
Krypton Lime green
Xenon  light blue
Radon Deep red

Is Helium a Noble Gas?

Helium is the first element in the gas group. Its boiling point is the lowest among all the elements. Its outermost shell is complete. So, It achieved having oxidation number zero.

Is Hydrogen a Noble Gas?

The answer is No. Its position is still not fixed in a periodic table. It is not an inert gas because its outermost shell is not fully filled (1s1).

Is Argon a Noble Gas?

Yes, it is an Inert gas. Due to its inert property, it is used in electric bulbs so that to escape the reaction inside it.

Is Neon a Noble Gas?

Yes, it’s an inert is placed in group number 18 below helium. it’s used in lighting the colorful hoarding boards.

Is Oxygen an Inert Gas?

No, It belongs to group 17 (halogen group).

Is Nitrogen an Inert Gas?

Nitrogen is not an inert gas. The electronic configuration is [He] 2s2p3. Third group: group VA called Nitrogen group.

Is Chlorine an Inert Gas?

Fifth group: group VIIA called Halogens. Chlorine is not an Inert gas.

Is Krypton an Inert Gas?

Krypton used with other rare gases in fluorescent lamps. Yes, it is an inert gas element.
