Four students presented different analogies to describe the formation of an ionic bond. Student A: A tug of war between seven middle school students and a high school student Student B: A small dog and a big dog tugging at a bone with equal strength

Chemical reactions occur when molecules or atoms collide so that the bonds between atoms break and new bonds form. breaking the bonds of the reactants requires energy; whereas, bond formation releases energy.
