Question

When two atoms of hydrogen combine to form a molecule of hydrogen gas, the energy of the molecule is (A) higher than that of the separate atoms (B) equal to that of the separate atoms (C) lower than that of the separate atoms (D) sometimes lower and sometimes higher

When two atoms of hydrogen combine to form a molecule of hydrogen gas, the energy of the molecule is lower than that of the separate atoms as a molecule is always more stable than the separate atoms, the energy of molecule is always less than that of separate atoms.
