The large difference between the melting and boiling points of oxygen and sulphur may be explained on the basis of
Solution
<p>The significant difference in the melting and boiling points of oxygen and sulfur can be explained by considering atomicity. </p>
<p><p>Oxygen exists as $\mathrm{O}_2$ (Atomicity = 2).</p></p>
<p><p>Sulfur exists as $\mathrm{S}_8$ (Atomicity = 8).</p></p>
<p>Due to sulfur's higher atomicity (forming S8 molecules), its melting and boiling points are considerably higher than those of oxygen.</p>
