Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
The electron configuration of iron, atomic number 26, is [Ar]3d64s2. The expanded electron configuration is 1s22s22p63s23p63d64s2.
Ground state configuration is nothing but the Electronic configuration of the metal in the ground state ie, the thing under normal condition. So, obviously the Ground state configuration of magnesium in [Ne] 3s2 (Atomic number 12).
The electron configuration for krypton (atomic number 36), as based on argon (atomic number 18), is [Ar] 3d10 4s2 4p6
The electron configuration of the element with the atomic number 39 (yttrium) is: [Kr]4d15s2.

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.
Magnesium's atomic number is 12. Therefore, it has 12 protons and 12 electrons. Filling in the first 12 atomic orbitals gives us the configuration of 1s2 2s2 2p6 3s2.
The sum of the superscript in an electron configuration is equal to the atomic number.
