Which element’s electron configuration is the most stable?

Which element’s electron configuration is the most stable?

The most stable electron configuration is that of a noble gas, due to the fact that its valence shell is filled. For helium, that means two valence electrons (a duet) in the 1s sublevel, and for the rest it means eight valence electrons (an octet) in the outermost s and p sublevels.

Which electrons are the most stable?

Atoms are at their most stable when their outermost energy level is either empty of electrons or filled with electrons. Sodium atoms have 11 electrons. Two of these are in the lowest energy level, eight are in the second energy level and then one electron is in the third energy level.

Which group has the most stable electrons?

The noble gases

Which is more stable configuration and why?

Electron configuration can predict the stability of an atom. When an atom’s all orbitals are filled, it becomes the most stable, thereby unreactive. Moreover, the most stable electron configuration possesses a full state of energy.
