Final answer:
Covalent bonding is primarily responsible for the characteristics of a bouncy ball.
Step-by-step explanation:
The characteristics of a bouncy ball are primarily due to the type of bonding present. In this case, covalent bonding is primarily responsible for the characteristics of a bouncy ball. Covalent bonds occur between two nonmetals, where electrons are shared between the atoms. These bonds result in a strong and flexible structure, which allows the bouncy ball to retain its shape and have elastic properties.
