Two hydrogen atoms interact to form a hydrogen molecule. Classify the following statements that describe the stages of bond formation in a hydrogen molecule according to the predominant force existing between the two hydrogen atoms.

a. The potential energy of the system is at minimum,
b. The two hydrogen atoms approach each other to form a bond,
c. The internuclear distance between the two hydrogen atoms is less than the bond length,
d. The potential energy of the system is positive,
e. The two hydrogen atoms form a stable hydrogen molecule,
f. The two hydrogen atoms start to combine to for the potential energy of the system is at minimum,

1. The two hydrogen atoms approach each other to form a bond,
2. Attractive force is predominant between the two atoms.
3. Repulsive force is predominant between the two atoms.
4. Attractive and repulsive forces balance each other.
5. There is no interaction between the two atoms
