There are several reasons why noble gasses are stable (as gasses at room temperature). First of all, there is the obvious full valence shell. The trend in the Periodic Table makes clear that the charge of the nucleus grows from left to right in every period. The attractive force towards the electrons therefore increases.

∙ 14y agoEach of the noble gases has a completely filled ring of electrons in the outer shell. This makes them less susceptible to gaining or losing electrons and this is what keeps them stable.
In more detail:
Every atom consists of a nucleus surrounded by one or more rings of electrons.
These rings hold either 2 (only for helium), 8 or 18 electrons.
Electron rings which are only partly filled are able to readily accept or lose their electrons and are inherently unstable.
If you look on a periodic table, you will see the noble gases on the right, all with completely filled electron rings.

∙ 11y agoNoble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.

∙ 13y agoIn chemistry, the term stable means non reactive, or a full outer energy shell. Noble gases are in group eight, so they each have eight valence (or outer energy level) electrons, with the exception of helium. This means that they have a completed outer energy level. A chemical reaction will only occur (without any form of energy being added) if the reaction will form a compound that is more stable than the two elements or compounds in question. Because noble gases already have a full eight valence electrons, no reaction with another element or compound could possibly cause them to become more stable, so any noble gas reaction has to have a form of energy added like heat or electricity. Hope this helps.

Elements that do not typically react with other elements are known as?
Elements in the Periodic Table that are not reactive are called the Noble Gases.
Is noble gases metals that are more reactive than the transition elements but less reactive than the alkali metals?
No, the noble gasses are nonmetals that are less reactive than all other elements.
What are unreactive nonmetals that do not react with other elements under normal conditions?
unreactive nonmetals are called noble gases
What do helium neon and fluorine have in common?
The are both 'noble' gases, elements with the full compliment of electrons in their outer electron shells.
What distinguishes noble gases from other nonmetals?
Unlikely other elements in the periodic table, noble gases rarely form compounds with other elements.
Elements that do not typically react with other elements are known as?
Elements in the Periodic Table that are not reactive are called the Noble Gases.
Is noble gases metals that are more reactive than the transition elements but less reactive than the alkali metals?
No, the noble gasses are nonmetals that are less reactive than all other elements.
What predominant feature characterize noble gases?
Their lack of reaction with other elements.
Are the Noble Gases very reactive with other elements and form many compounds?
No. The noble gases are inreactive and don't form compounds with other elements. This is because they have a full outer shell of electrons.
Why dont noble gases need to make compoundswith other elements?
Noble gases have completely filled orbitals (octet of electrons), they are stable and chemically inert (non-reactive).
What are unreactive nonmetals that do not react with other elements under normal conditions?
unreactive nonmetals are called noble gases
What are the elements in Group 17-18 called?
The Group 18 elements are called the noble gases or sometimes inert gases. Wikipedia has information on the noble gases, and a link is provided.
What do helium neon and fluorine have in common?
The are both 'noble' gases, elements with the full compliment of electrons in their outer electron shells.
What distinguishes noble gases from other nonmetals?
Unlikely other elements in the periodic table, noble gases rarely form compounds with other elements.
What does the term noble mean in noble metals and noble gases?
There are no "noble metals". The "noble" connotation for "noble gas" is that in society, the "noble" people don't interact with the average people. "Noble" or inert gases do not take part in any regular chemical reactions. The individual atoms don't form elements or compounds.
Is noble gases the least reactive elements on the periodic table?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements).
Are Group 8A element unreactive elements known as transition metals?
Group 8A, also known as group 18, are very non-reactive. However, they are all gases, not transition metals. Transition metals are the large family of elements in the middle of the table in between groups 2 and 13 (2A and 3A). Group 8A are the noble gases.
