Explain the process of ionic bond formation between K (potassium, a metal) and Br (bromine, a nonmetal).

Answer:

K donates, or transfers, one electron to bromine, which has 7 electrons. Both K and Br are now stable with 8 electrons. K becomes a positive ion and Br becomes a negative ion. The positive K ion and the negative Br ion attract each other to form an ionic bond.
