B. Molecules in both the metal and the surrounding air will start moving at higher speeds.
<span>Effective nuclear charge is an estimate of the charge experienced by the valence electrons.
</span><span>Sulfur has 6 valence electrons and a charge of 6+.
</span><span>The 3s electrons in sulfur are the 3p electrons, because the former spend more time closer to the nucleus.</span>
<span>Using Slater's Rules, effective nuclear charge of sulfur is +5.5.
2) No!</span><span> The Zeff doesn't differ from ions and atoms of the same element.</span>
Solvation is the process in which molecules of a solvent attract the particles of a solute.
