Why are bromine and potassium likely to react with one
another?

Potassium reacts with Bromine to produce Potassium Bromide. ... Bromine needs to gain one electron to have a noble gas configuration or 8 valence electrons. Potassium needs to lose one, so they make a perfect pair to transfer electrons in an ionic bond

Hope this helped! :)

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
