How many unpaired electrons are present in a single molecule of diatomic sulphur () in its vapor sta — p Block Elements Chemistry Question

💡 Solution & Explanation

At high temperatures (~1000 K), sulphur vapor exists mainly as $S_2$ molecules. Similar to the $O_2$ molecule, $S_2$ possesses two unpaired electrons in its degenerate antibonding $\pi^*$ molecular orbitals, making it paramagnetic.
