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 .
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
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-

The sodium atom becomes a sodium cation, and the chlorine atom becomes a chloride anion.
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.
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.
