1s^2 Note: The "^" symbol means the the following number is in the form of a superscript.
to find the electron dot configuration of an element simply draw dots, symbolizing valance electrons, in a way that they are farthest from each other around the symbol of the element you are using.
The electron configuration of magnesium is 1s2 2s2 2p6 3s2. Mg+ has one less electron (electrons have negative charge, so a positive charge is a lack of electrons) so you remove one from the outermost orbital: 1s2 2s2 2p6 3s1, or simply [Ne] 3s1.
The electron configuration of boron is [He]2s2.2p1.
Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.
The shorthand electron configuration of magnesium is [Ne]3s2.
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 abbreviated electron configuration of sodium is [Ne]3s1.
The electron configuration of sulfur is [Ne) 3s2.3p4.
Argon does not have an electric configuration.
[Ne] 3s2 3p6
The electron configuration of aluminum (Al) is [Ne] 3s2 3p1
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.
The electron configuration of argon is [Ne] 3s2 3p6, where [Ne] represents the electron configuration of neon. Argon has 18 electrons, with 2 electrons in the 3s orbital and 6 electrons in the 3p orbital.
The electron configuration of sulfur is [Ne]3s2.3p4.
The electron configuration of aluminium is [Ne]3s2.3p1.
If you think to the electron configuration of magnesium this is: [Ne]3s2.
