The electron configuration of americium is [Rn]5f7.7s2.
Well first of all your question does not make any sense due to the fact that Electron configuration and Noble gass configuration are two completely different things Electron configuration: 1s22s22p63s23p64s23d104p65s24d105p66s24f145d106p67s2 Noble gas configuration: [Rn] 7s2
[Xe] 4f3 6s2
This is obviously the Nobel gas argon.
These are Nobel gases, have stable elecronic configuration i.e. complete duplet (He) and octat e.g. Ne, Ar etc .

No - but the potassium ion does
[Xe] 4f3 6s2
It is [Kr] 4d2 5s2
A Nobel gas, or an atom with a filled valance shell. In Nobel gas configuration.
[Xe] 4f3 6s2
I assume you mean the Nobel gas electron configuration abbreviation for barium.[Ne] 6s2=======
Cs does not have a nobel gas electron configuration, as it contains one valence electron in its outermost s orbital. Be3+ also does have a nobel gas electron configuration, as this occurs when Be has a 2+ charge (the typical Be ion is Be2+).
If you think to the electron configuration of promethium this begin with [Xe].
Lithium electron configuration: 1s2 2s1, or in shorthand: [He] 2s1 Thus in LiF the Li cation (Li missing one electron to get its nobel gas configuration of He) it is Li+: 1s2 2s0, or in shorthand: [He] 2s0, This ion does NOT have 8 (octet) electrons, although it has a nobel gas configuration of He: 1s2.
