What does the minimum of a potential-energy curve for two atoms represent?
A.Bond length and bond energy
B.The transition state
C.The point where atoms stop moving
D.Ionization energy
Explanation
Core Concept
As atoms approach, attractions lower potential energy until a minimum; pushing closer makes repulsion dominate and energy rises. The minimum's position gives bond length, and its depth gives bond energy.
Correct Answer
ABond length and bond energy
