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).
3S^2. If you understand electron configuration, this should make sense.
Magnesium has three electron shells.
The electron configuration of magnesium is [Ne]3s2.
4 sublevels 1s 2s 2p & 3s
1s2 2s2 2p6 3s2
undiscovered...yet, but there are a few...go forward 50 years and see
filled energy sublevels
In Neon atom the 10 electrons are present in two principal energy levels, 2 in ist and 8 in 2nd level.
A filled highest occupied principal energy level
Group 18 or the noble gases.
Nobel gases are said to have completely filled third principle energy level. One example is Argon which is a noble gas.

the one that is completely filled
S and P
filled energy sublevels
Completely filled octet.
In Neon atom the 10 electrons are present in two principal energy levels, 2 in ist and 8 in 2nd level.
Their outer energy levels are completely filled.
D has 5 orbitals and can be filled with up to 10 electrons.
A filled highest occupied principal energy level
it is called complete or completely stable
Completely filled octet.
