The electron configuration of aluminium is [Ne]3s2.3p1.
The shorthand electron configuration of magnesium is [Ne]3s2.
Phosphorus has an electron configuration of 1s2 2s2 2p6 3s2 3p3. Another way to write that is [Ne] 3s2 3p3. The [Ne] represents the fact that the beginning of phosphorus' electron configuration is the same as Neon's.
The electron configuration of sulfur is: [Ne]3s23p4.
Chloride Cl-: Ne,3s2,3p6 : has 1 valence electron accepted from metal XChlorine Cl : Ne,3s2,3p5 : neutral can donate 1, 3, 5 or 7 val. electrons, remains: 3p5->4,2,0 and 3s2->0 respectively, '->' means 'lowering to')Chlorine? Cl?: Ne,3s2,3p65 as in the questioned: unknown 65 is impossible,(mail my Mess.Board if you can give an other question.JdQ)
The electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5.

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
a core electron, is an electron that isn't a valance electron. That means any electron that is not on the outer shell of an atom
2 core electrons and 8 valence electrons are there in N3- ion.
The electron is an elementary particle. This means that it cannot be broken down further. Therefore, an electron does not have a "core".
The electron configuration of aluminum (Al) is [Ne] 3s2 3p1
If you think to the electron configuration of magnesium this is: [Ne]3s2.
