The electron configuration for neutral Chlorine is 2.8.6.
1s2,2s2,2p6,3s2,3p3
Neutral calcium's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. Ca2+ is the ion of calcium, which means that it has 2 less electrons than neutral calcium. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6.
1 additional electron will give chlorine 8 in the valence. You can see in the Periodic table, that Chlorine is next to Argon ( 1 to the left of it) so it needs 1 more electron to have the same configuration as Argon.
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 wide variance in their electronegativity. Chlorine has such a powerful electronegativity compared to sodium that it " takes " the sodium's electron into it's valance shell. Thus. Na + and Cl - attract each other and form NaCl sodium chloride.
The electron configuration of arsenic is: [Ar]4s23d104p3.

Losing an electron cesium has a noble gas configuration.
Electron configuration is a term applied to chemical elements not to compounds.

Two electrons
One, but there is a catch. One magnesium atom will combine with two chlorine atoms to make magnesium chloride (MgCl2). The magnesium will give one electron to eachof two chlorine atoms to create this metal salt.

' I love you so much , Chlorine, that I am going to give you my outer valance electron. '
bonding. The ionic bonding occurs because sodium is a metal while chlorine is a halogen. Each of these elements have the typical atomic structure: a nucleus with protons and neutrons, and numerous energy levels which the electrons "inhabit". Sodium and Chlorine have a strong tendency to want to gain what is called a noble gas configuration (their outer layer completely full of electrons). Since sodium has one extra electron, it just needs to give that one electron up in order to gain its noble gas configuration hence, it's an "electron donor". Chlorine has one less electron than it needs to gain a noble gas configuration, so it's looking to take one from sodium, making it an electron "acceptor". The gain or loss of an electron gives each of these atoms and electric charge: sodium a positive, chlorine a negative. Because opposite charges attract, these two want to stick to each other. In a crystal lattice, each one wants to minimize its repulsions and maximize its attractions, so it forms a pattern of opposites. i hope that answered your question.
