The sodium atom becomes a sodium cation, and the chlorine atom becomes a chloride anion.
Chlorine needs to gain (-1) one valence electron to become unreactive like Argon. The reason why Argon is unreactive is because it had 8 valence electrons.
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.
Cl:Cl Since each of the chlorines in the molecule is sharing one electron with the other they both get an octect. They only share one of their electrons with the other. So 7+1=8The chlorine atoms could share a pair of valence electrons.
A sodium atom loses an electron which is gained by the chlorine atom. This results in the formation of a sodium ion with a 1+ charge and a chloride ion with a 1- charge. The electrostatic attraction between the oppositely charged ions forms an ionic bond between the ions.
Chlorine atoms have 7 valence electrons and need only 1 more in order to become stable (having 8 valence electrons). It takes much less energy to add an electron to a chlorine atom than it does to remove 7 valence electrons, so the chlorine atom gains one electron and becomes a negative ion with a 1- charge. The same thing is true of oxygen, except that it has 6 valence electrons, so it will gain 2 electrons and becomes a negative ion with a 2- charge.
when sodium valence electron is transferred to chlorine , both atoms become ions . the sodium atom becomes a positive ion . the chlorine atom becomes a negative ion .
when sodium valence electron is transferred to chlorine , both atoms become ions . the sodium atom becomes a positive ion . the chlorine atom becomes a negative ion .

A negatively charged "ion".
Chlorine needs to gain (-1) one valence electron to become unreactive like Argon. The reason why Argon is unreactive is because it had 8 valence electrons.
Sodium becomes a cation and chlorine becomes an anion.
sodium becomes positive ( as it loses a negative electron but still hs the same number of + protons) with a single + charge. chlorine becomes negative ( as it gains an extra negative electron but still hs the same number of + protons) with a single - charge. NaCl -------> Na+ Cl-
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.
The sodium atom, Na, is ionized, giving it's electron to the chlorine, Cl. Therefore, one electron is transferred from the sodium to the chlorine, forming Na+ and Cl- ions and an ionic bond.
The atoms of both elements have seven valence electrons and a strong tendency to abstract, from a less electronegative atom, an electron to complete their valence shells and thereby become an anion.
Each separate chlorine ion will have a charge of 1-. This is because chlorine has 7 valence electrons, so it needs one more electron to become stable.
11 electrons makes the third energy level complete. One
