Q1 Why are two balls connected by a spring a good model for two atoms connected

Question

Q1 Why are two balls connected by a spring a good model for two atoms connected by a chemical bond? (a) If the two atoms get farther apart than the equilibrium interatomic distance, they attract each other. (b) Each spring represents a real microscopic coiled metal wire that connects two adjacent atoms. If the two atoms get closer together than the equilibrium interatomic distance, they repel each other. (c) The magnitude of the foree one atom exerts on another is proportional to the stretch or compression of the bond between them.

Explanation / Answer

In my opinion option (a) and option (c) are the correct answers.

Option (b) will be out because, there is no real metallic wire connection between the two atoms. The sping and balls model is only for the assumption and to understand the interatomic behaviours of the atoms.
