1s22s22p6
The shorthand electron configuration of magnesium is [Ne]3s2.
Sodium has the configuration Ne 3s2 . Sodium is group-1 element.
Argon does not have an electric configuration.
[Ne] 3s2 3p6
[Ne] 3s2 3p2
The electron configuration of aluminium is [Ne]3s2.3p1.
The electron configuration of sulfur is [Ne]3s2.3p4.
The noble gas configuration of magnesium is [Ne] 3s^2. This indicates that magnesium has the same electron configuration as the nearest noble gas, neon, with an outer shell containing 2 electrons in the 3s orbital.
The noble gas electron configuration of chloride ion (Cl-) is [Ne]3s^23p^6, which is equivalent to the electron configuration of argon. This means that chloride has gained an extra electron compared to neutral chlorine, resulting in a full outer electron shell and a stable, closed-shell configuration.
Sodium has the configuration Ne 3s2 . Sodium is group-1 element.
The abbreviated electron configuration for argon is [Ne] 3s^2 3p^6. The [Ne] represents the electron configuration of the noble gas neon, which has the same electron configuration as the inner electrons of argon.
The configuration Ne 3s2 3p6 represents the electron configuration of the noble gas neon, which has 10 electrons in total.
