NEET Chemistry Covalent Bond MCQ Question
Consider a diagram showing two hydrogen atoms approaching each other, each with its electron cloud represented. What happens to the potential energy of the system as the atoms form a covalent bond?
Potential energy decreases as attraction overcomes repulsion.
Potential energy increases as repulsion overcomes attraction.
Potential energy remains constant as the forces are balanced.
Potential energy increases due to the increase in atomic size.
Correct Answer
Detailed Explanation
As two hydrogen atoms approach each other, the attractive forces between the nuclei and electrons reduce the potential energy, leading to bond formation when these forces balance repulsive forces.
