(3) loses one electron and becomes positively charged Lithium has one valence electron and Bromine has seven. Therefore Lithium will give up its one to Bromine for both to have an octet
loses one electron ;
In the reaction of lithium with bromine, each lithium atom loses one electron and becomes a positively charged ion (Li⁺). The correct answer is option (3). This process allows lithium to achieve a stable electron configuration similar to that of noble gases.
