The reason for the noble gases gases' electron configurations to allow them to have a similar property of having a low reactivity is because they all have a full set of electrons in their outermost energy level.
Because they all have8 valence electrons which means there outer shell is filled with electrons
they dont have any common properties except that when halogens gain one electron, they achieve the electronic configuration of the nearest noble gas.
Noble gases have a stable electron configuration with a full outermost energy level, which makes them very unreactive. This means that they do not easily form compounds with other elements. They have low boiling and melting points, and are colorless and odorless gases at room temperature. Additionally, noble gases have high ionization energies, which means it requires a large amount of energy to remove an electron from their outermost energy level.
nitrogen will get noble gas configuration by adding three more electrons.
If alkali metals loses one electron, they achieve the electronic configuration of the nearest noble gases.
Inert gases are the most stable ones, so if we try to add another electron, the stable electronic configuration is disturbed. So, we have supply energy for this process. Hence, electron gain enthalpy is positive.

it only fills the S sublevel
By acquiring noble gas configuration elements become stable .
The group of elements that have a stable electron configuration are the noble gases.
Helium's electron configuration is 1s2. Neon's electron configuration is 1s22s22p6. All of the rest of the noble gases, like neon, have the maximum number of electrons in their outermost s and p orbitals (valence shells), which is eight.

K+And the K ion configuration is 1s2 2s2 2p6 3s2 3p6Noble gases have the configuration up to 3p6Pseudo noble gases have it up to 3d10
nitrogen will get noble gas configuration by adding three more electrons.
They have completely filled shells, with eight valence electrons.
Noble gases have a stable electron configuration. So they are less reactive.
