[Xe] 4f3 6s2
The electron configuration of americium is [Rn]5f7.7s2.
Argon has the same electron configuration as N3. Both have 10 electrons with the electron configuration 1s2 2s2 2p6.
neon
The electron configuration of cesium in noble gas form would be [Xe] 6s^1. This indicates that cesium has the same electron configuration as the noble gas xenon in addition to one extra electron in the 6s orbital.

Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.
The electron configuration of americium is [Rn]5f7.7s2.
Caesium (Cs) has 55 electrons, and it will need to lose 1 electron to achieve a noble gas electron configuration. This is because Cs is in Group 1 of the periodic table, so losing 1 electron will leave it with the same electron configuration as the noble gas element in the previous period (Xenon).
I assume you mean the Nobel gas electron configuration abbreviation for barium.[Ne] 6s2=======
If you think to the electron configuration of promethium this begin with [Xe].
The noble gas that has the same electron configuration as the oxygen atom in a water molecule is neon (Ne). Both have a full valence shell with 8 electrons, making them stable and unreactive.
The Alkali Metals loose one electron in order to achieve a nobel gas configuration.
Helium IS a Nobel gas and heads that group. It may not have the full 8 electron octet, but it is just as naturally non-reactive as the other Nobel gases.
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+).
No, potassium does not have a noble gas electron configuration. The noble gas configuration for potassium would be [Ar] 4s¹, but instead, potassium has the electron configuration 1s² 2s² 2p^6 3s² 3p^6 4s¹.
nobel gas is a gas that cannot react with another gas
