what is noble gas configuration in chemistry?
212878
Noble gas configuration is the tendency of chemical elements to gain or lose electrons to reach the electronic configuration of a noble gas. This may refer to: Octet rule, the electronic rule for main group elements.

Oxygen is not a noble gas. Oxygen is a gas in the group 6 of the periodic table which needs 2 more electrons to complete the outermost shell. ... The noble gases are Helium, Argon, Neon, Xenon, Krypton and Radon . These are the only elements that can exist in atomic form without being highly reactive.

The noble gases are the chemical elements in group 18 of the periodic table. ... Other characteristics of the noble gases are that they all conduct electricity, fluoresce, are odorless and colorless, and are used in many conditions when a stable element is needed to maintain a safe and constant environment.

Helium is slightly different than the other noble gas elements. It only has two electrons in its outer shell so its valence electron configuration is 1s2.

Helium is slightly different than the other noble gas elements. It only has two electrons in its outer shell so its valence electron configuration is 1s2. ... The noble gases are happy with their completely filled valence shells.

A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium's noble gas configuration becomes [Ne]3s1.

Other characteristics of the noble gases are that they all conduct electricity, fluoresce, are odorless and colorless, and are used in many conditions when a stable element is needed to maintain a safe and constant environment. ... This chemical series contains helium, neon, argon, krypton, xenon, and radon.

Noble gas electron configurations are easier to write because they are shorter than full electron configurations. To understand the chemistry of an element, it's most important to know about the electrons in the highest energy levels. Lead has four valence electrons and its chemistry is based on this fact.

Octet Rule. The noble gases are unreactive because of their electron configurations. The noble gas neon has the electron configuration of 1 s 2 2 s 2 2 p 6 . It has a full outer shell and cannot incorporate any more electrons into the valence shell.

The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don't react with anything. For this reason they are also known as inert gases.

Noble gases are placed in a separate group of the periodic table because they are inert elements. They are unreactive as their valence shells are completely filled with electrons.

All noble gases have full s and p outer electron shells (except helium, which has no p sublevel), and so do not form chemical compounds easily. Because of their high ionization energy and almost zero electron affinity, they were not expected to be reactive.

How Noble Gases Form Compounds. Helium, neon, argon, krypton, xenon, radon have completed valence electron shells, so they are highly stable. The filled inner electron shells tend to provide a sort of electrical shielding, making it possible to ionize the outer electrons.

Noble gas. ... Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

Argon is a noble gas so as such it does not form any compounds as it is very stable . It is monoatomic in the elemental state. Argon is an element belonging to group 18. Group 18 consists of Noble gases: Helium, Neon, Argon, Krypton, Xenon and Radon.

Argon. Argon is a chemical element with symbol Ar and atomic number 18. Classified as a noble gas, Argon is a gas at room temperature.

Noble gases have highly stable fully filled electronic configuration which makes removal of electron extremely difficult. This accounts for the high ionisation enthalpy of noble gases.
