Stability of Cl vs Cl-

Since Cl has 7 valence electrons and only needs 1 more to complete its octet, once it obtains an electron to become Cl-, is it more stable as this ion? And does stability mean that it is less reactive?

Yes, because it now has a full octet it is more stable.

The more stable it is the less reactive it will be because it already has a more desirable amount of electrons. Once Cl gains an electron it has a full octet and does not have a desire to gain any more electrons. Its properties will become similar to that of Argon.

Having a full octet means the atom is more stable and therefore less reactive because it does not need to gain or lose any electrons.

noble gases and other elements as ions like Cl- with full octets are more stable and less likely to react with other elements

Chlorine is very reactive because of how close it is to filling a full electron shell. Since it only needs only more to complete a shell as opposed to losing 7, Cl- is the most common form. This is also why we see Na+ a lot. The Na needs to lose an electron to have a full valence shell. Hence, NaCl.

After Cl gains another electron, it has an octet. This means Cl- is more stable and less reactive because it now has a full set of valence electrons. Cl- will no longer look for more electrons.
