On a charge : The experimental capacitance per cluster ( C ) as a function of charge state ( z , see picture) confirms the quantized charging of “ligand‐free” metal clusters in an ionic liquid. DFT calculations indicate a switch in orientation of the ionic shell around the clusters when the sign of the charge changes, and explain the maximum capacitance at zero charge.
