in sodium chloride chlorine gains an electron and the bond formed between then is ionic.
Chlorine gains one electron when it forms an ion, becoming a chloride ion with a negative charge.
Sodium would react strongly with chlorine because sodium has one electron in its outer shell, which it can easily lose to become stable. Chlorine has seven electrons in its outer shell and can gain one electron to achieve stability. When sodium and chlorine react, sodium loses an electron to chlorine, forming sodium chloride (table salt).
Chlorine will gain one electron in order to establish a full outer shell of electrons. Chlorine atoms have 7 valence electrons, but with one extra electron, it can establish a stable octet.
sodium has in his orbits or shell 2,8,1 so it is easier for it to loose this electron to reach his stability form and for that it is very reactive with most of the chemical elements otherwise the chlorine is very active specifically with Oxygen O2 which transform it to chlorites, chlorates, and perchlorate
ionization energies of mg is less than chlorine because chlorine requires only one electron to complete its octet so it will not prefer to loose its electron morover its electronegativity is also higher and it is of smaller size than mg so electtron removal is difficult

Sodiumbeing in group 1 needs to loose 1e- to become stable. Chlorine being from group 17 needs to gain 1e- to become stable. Sodium gives its extra electronto the chlorine atom. Now both have 8 electrons in their valence and are stable. The sodium gets a positive charge because it lost and electron. The chlorine gets a negative charge because it gained an electron.This creates an ionic bond

The sodium atom has 1 electron in its outermost shell. When forming an ion it donates this electron giving it an overall charge of +1 (having lost a negative charge). Chlorine atoms have 7 electrons in their outermost shells. When forming an ion these are more likely to take an electron from another atom to form a complete octet (gaining a negative charge) thus it becomes -1. Both atoms will gain or loose 1 electron, hence why they have the same valency, however the electrovalency depends on whether this charge becomes positive or negative. Hope this helps!
This electron is the only one in a new outermost electron shell as you progress through the periodic table. So it is relatively easy for it to hop off and join to a Chlorine atom, for example, which is one short of a completed shell. So it's good in forming ionic compounds,
The Alkali Metals loose one electron in order to achieve a nobel gas configuration.
Because the Chlorine gas doesn't have enough attraction to itself to condense into a solid but the MgCl2 doesn't have enough energy to shake it's bonds loose and become a gas. The MgCl2 is solid because they stuck together by different types of bonding but those bonds aren't strong enough in Cl.
The chloride ion has a negative charge; Cl-. You can tell because chlorine is on the right side of the periodic table in the second column from the right. All elements in this column have a charge of -1.
They would form an ionic bond and combine to create sodium chloride, or table salt. The positive sodium ion would be attracted to the negative chlorine ion, leading to the formation of a stable compound with a neutral charge.
