Under ordinary condition hydrogen atom is more stable than hydrogen molecule.Question 3Answera.Falseb.True

Analysis of the Stability of Hydrogen Atom vs. Hydrogen Molecule

1. Understanding the Comparison:

   • A hydrogen atom (H) consists of a single proton and an electron, while a hydrogen molecule (H₂) is made up of two hydrogen atoms bonded together.

2. Bonding and Stability:

   • The formation of the hydrogen molecule involves the sharing of electrons between the two hydrogen atoms, creating a covalent bond. This bond lowers the energy of the system compared to two separate hydrogen atoms.

3. Energy Considerations:

   • Generally, atoms tend to achieve a more stable state when they form chemical bonds, as seen in diatomic molecules like H₂. The energy released during the formation of a bond is a sign of increased stability.

4. Final Conclusion:

   • Given that a hydrogen molecule (H₂) has lower energy and is more stable than separate hydrogen atoms, the correct answer to the statement "Under ordinary conditions, hydrogen atom is more stable than hydrogen molecule" is:

Final Answer

a. False
