Highlights: [•] Uncoated and capped Ag NPs of about 3–5nm and 10–12nm in diameter were studied. [•] Resistive switching was found in the tunneling spectra at smaller uncapped NPs. [•] Anodic oxidation of uncapped NPs to Ag2O and AgO nontrivially depends on their size. [•] Capping of Ag NPs impedes the anodic oxidation. [ABSTRACT FROM AUTHOR]
