When lithium reacts with bromine to form theĀ compound LiBr, each lithium atom:
(1) gains one electron and becomes a negatively
charged ion
(2) gains three electrons and becomes a negatively
charged ion
(3) loses one electron and becomes a positively
charged ion
(4) loses three electrons and becomes a positively
charged ion

Verified Answer :

(3) loses one electron and becomes positively chargedĀ 
Lithium has one valence electron and Bromine has seven. Therefore Lithium will give up its one to Bromine for both to have an octet

Answer:

loses one electron
