Why noble gas do not form molecules?

Answer 1

The Noble gasses already have a full valance shell so they don't need any more Electrons. This tends to make them avoid other atoms because they are totally neutral.

Answer 2

Noble gases do not easily form molecules because they have a full valence shell of electrons, making them stable and unreactive. This means they do not have a tendency to gain, lose, or share electrons with other atoms to form bonds. Their complete valence shells give them little incentive to form chemical bonds with other elements.

Answer 3

They do, in 1933, Linus Pauling predicted that the heavier noble gases would be able to form compounds with fluorine and oxygen. Specifically, he predicted the existence of krypton hexafluoride and xenon hexafluoride (XeF6), speculated that XeF8 might exist as an unstable compound, and suggested that xenic acid would form perxenate salts. These predictions proved quite accurate. The heavier noble gases have more electron shells than the lighter ones. Hence, the outermost electrons experience a shielding effect from the inner electrons that makes them more easily ionized, since they are less strongly attracted to the positively-charged nucleus. This results in an ionization energy low enough to form stable compounds with the most electronegative elements, fluorine and oxygen.

Answer 4

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

Answer 5

The noble gases are unreactive and because for two atoms to form a molecule they need to chemically react and for chemical reactions to take place 2 or more atoms are needed to react to form a molecule.

Answer 6

Noble gases have completely filled orbitals / electron energy shells. They are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons and they do not form compounds / ions.

Answer 7

Noble gases have completely filled orbitals. Their valence orbitals are completely filled, have 8 electrons and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements) and dont from compounds generally

Answer 8

To add to what Dark Maiden has said, you may be curious as to why noble gases are unreactive. Elements react with one another because they either share or exchange electrons. The way they share electrons with other elements depends on the quantum mechanical behavior of the electrons and their potential energies. The noble gas atom has an electron potential energy structure that does not allow it to share or exchange electrons with any other atom, therefore it can't react.

Answer 9

They don't generally form ions because they already have a full valence electron shell, a full 8, or 2 for helium.

Answer 10

noble gases have a full octet, and need not bond, as they do not need any more valence electrons
