What makes group 18 gases. noble?

Answer 1

noble gases are all very stable because they each have the maximum amount of electrons in their outer shell (8 for all except helium which has 2) they are also nonreactive and cannot form compounds

Answer 2

Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). They are chemically inert (or do not react with other elements).

Answer 3

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

Answer 4

Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable octet electronic configuration. Hence they are chemically inert and generally do not form compounds under normal conditions.

Other group elements do not obey octet rule and are thus generally reactive.

Answer 5

because group 18 has the full amount of valence electron in there outer shell

Answer 6

Noble gases all are very STABLE they all have a maximum amount of electrons...but the big reason is because, they are nonreactive and cannot form compounds, like most elements can.

Answer 7

Group 18 is called the Noble gasses because group 18 has all 8 of the valence, therefore it is complete and doesn't need to borrow or bond with another element.

Answer 8

Their outer valance shells are filled and they are very unreactive in nature.

Answer 9

noble gas elements have completely filled p-orbitals and have are stable than elements or other group.
