Question

-When two H-atom approach each other to form H2 molecule, the potential energy diagram obtained is (d interatomic distance)​

Answer 1

Answer:

When the potential energy is zero, a covalent bond is formed. When the distance between two hydrogen atoms is 0.74 Å, a covalent bond is formed. When two hydrogen atoms are very far apart, the potential energy approaches zero. This is because as the distance increases, the forces get less and less effect on each other.
