1s2, 2s2 2p6, 3s2
In my class Mg would be written (level 1, 2, 3, ..) as 2, 8, 2
Energy Level => Max numbers of electrons is
1 => 2
2 => 8
3 => 18
4 => 32
ELECTRONIC CONFIGURATION OF Mg IS

SANDEEP SONI
The electron configuration of Mg is [Ne]3s2. Magnesium is a divalent element.
Magnesium's atomic number is 12. Thus, it has 12 electrons per atom. Filling in the first 12 electron orbitals gives the configuration of 1s2 2s2 2p6 3s2.
12Mg: [Ne] 3s2 or 1s2 2s2 2p6 3s2
1s2 2s2 2p6 3s2
or
[Ne] 3s2
Mg: 1s22s22p63s2
1s22s22p63s2
1s2 2s2 2p6
The shorthand electron configuration of magnesium is [Ne]3s2.
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
Mg 2+ Has the same electron configuration as neon. Two electrons lost to do this.
The electron configuration for Mg2+ is 1s22p22p6.
Magnesium is the period 3 alkaline earth metal. Thus, its electron configuration is 1s2 2s2 2p6 3s2. The shorthand version of this is [Ne] 3s2 since neon's electron configuration is 1s2 2s2 2p6.
If you think to the electron configuration of magnesium this is: [Ne]3s2.
Cl
The shorthand electron configuration of magnesium is [Ne]3s2.
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
Mg 2+ Has the same electron configuration as neon. Two electrons lost to do this.
[Ne]3s2
The element magnesium (atomic number 12) has the electron configuration of1s2 2s2 2p6, 3s2or the noble gas abbreviation [Ne] 3s2(see related link)The electron configuration for neutral magnesium (Mg) is 1s22s22p63s2. The ion, Mg2+, has two electrons fewer, so the outer two electrons are removed from the electron configuration. This changes the electron configuration to 1s22s22p6, which is the same electron configuration as the noble gas neon.
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 for Mg2+ is 1s22p22p6.
Magnesium is the period 3 alkaline earth metal. Thus, its electron configuration is 1s2 2s2 2p6 3s2. The shorthand version of this is [Ne] 3s2 since neon's electron configuration is 1s2 2s2 2p6.
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
The electron configuration for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
