Z=12 is magnesium. The electron configuration 1s2 2s2 2p6 is isoelectronic with neon, so my best guess is that it's a convoluted way of writing Mg++.

Why D2 and z12 are not isomorphic?

D2, the dihedral group of order 4, consists of rotations and reflections of a square, while Z12, the cyclic group of order 12, is generated by the addition of integers modulo 12. D2 is not cyclic, as it cannot be generated by a single element, whereas Z12 is cyclic, generated by 1. Furthermore, the structure of the groups differs: D2 has elements of order 2 (the reflections) and elements of order 4 (the rotations), while Z12 has elements of various orders that are consistent with a cyclic structure. Hence, their different algebraic structures confirm that D2 and Z12 are not isomorphic.

How many valence electrons does oxygen gain?

Oxygen tends to gain two electrons to complete its "octet", making it O2- with the electron configuration 1s22s22p6


What elements has the electron configurations?

That's correct! Sulfur (S) is in the third row, so it has electrons in the third energy level. The first two levels are completely filled, giving 1s22s22p6 and it has six electrons in the third level, giving 3s23p4.


Electron configuration of a noble gas?

Helium's electron configuration is 1s2. Neon's electron configuration is 1s22s22p6. All of the rest of the noble gases, like neon, have the maximum number of electrons in their outermost s and p orbitals (valence shells), which is eight.


A sodium atom has an electron configuration of 1s22s22p63s1 If the sodium atom becomes ionized its new electron configuration will be the same as which element?

If a sodium atom loses an electron to become a Na+ ion, its electron configuration will be the same as neon (1s22s22p6). Both sodium and neon have stable electron configurations.

What i s the configuration for Mg?

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.
