Noble Gases

hey guys i need some help how do you determine the noble gas of an element. For example the noble gas for AL (13) is neon.
If you can help please post. thanx

I think what you are asking is now does one determine the noble gas whose electronic structure is the same as that for any given element in its most common oxidation state.

To do this - start by determining the most common oxidation state (listed in WebElements), which for aluminium is Al(III). This has the electronic structure 1s2.2s2.2p6 - which is the same as that of neutral neon.

Similarly sodium anbd magnesium adopt the neon structure in their most common oxidation states - Na(I) and Mg(II)

However sulphur and chlorine adopt the argon structure 1s2.2s2.2p6.3s2.3p6 in their most common oxidation states which are S(-II) and Cl(-I).
