Sulfur can both gain and lose electrons when forming ions. It can gain two electrons to form a sulfide ion (S2-) or lose two electrons to form a sulfide ion (S2+).
Sulfur needs to gain 2 electrons to have the electon configuration of Argon
Nitrogen gains 3 electrons, oxygen gains 2 electrons, sulfur gains 2 electrons, and bromine gains 1 electron when forming ions.
Bromine will gain one electron when forming an ion to achieve a full outer electron shell. This will give it a stable electron configuration.
Sulfur gains 2 electrons to become stable.
Sulfur can exhibit a negative valency because it can gain electrons to achieve a stable electron configuration, typically by forming sulfide ions (S2-). This allows sulfur to reach a more stable octet electron configuration, as it gains two electrons to have a full valence shell.

Chlorine prefers to gain one electron to achieve a full outer electron shell, forming a -1 ion. On the other hand, sulfur has two extra electrons to reach a full outer shell, leading to the formation of a -2 ion. This difference in electron configuration accounts for why chlorine forms a -1 ion while sulfur forms a -2 ion.
Yes, if a chlorine atom attracts an electron from sodium, the chlorine atom would gain an extra electron and become negatively charged, forming a chloride ion (Cl-). Sodium, on the other hand, would lose an electron and become positively charged, forming a sodium ion (Na+).
Bromine typically gains one electron when forming an ion to achieve a stable electron configuration. The electron configuration for a bromine ion is [Kr] 4d10 5s2 5p6, which is the same as that of a noble gas.
Bromine is most likely to gain one electron when forming an ion, as it is in Group 17 of the periodic table (halogens) with 7 valence electrons. By gaining one electron, bromine achieves a stable octet and forms a Br- ion.
