Question

Which of the following is the most stable state when two atoms come closer to each other to form a molecule?

• A. When the bond is formed, the energy is minimum
• B. When the atoms touch each other, the energy is zero
• C. When the atoms are isolated, the energy is minimum
• D. None of these

Answer 1

The correct option is A When the bond is formed, the energy is minimum

Atoms form chemical bonds in order to make their outer electron shells more stable. The type of chemical bond maximizes the stability of the atoms that form it.

During the formation of the chemical bonds, the release of the energy takes place. Thus, when the bond is formed, the energy is minimum and stability is maximum.

Hence, the correct answer is option $\text{A}$.
