Question

Bromine is an element that often gains an electron to become a negatively charged ion. Potassium is an element that often loses an electron to become a positively charged ion.
Why are bromine and potassium likely to react with one another?

Answer 1

Potassium reacts with bromine to produce Potassium Bromide, because bromine has a (-) charge while potassium has a (+) charge. Bromine needs to gain one more electron to have a noble gas configuration or 8 valence electrons, & potassium needs to lose one so they make a transference of electrons in an ionic bond.
