We report here on the successful oxidation of element 102, nobelium (No), on an atom-at-a-time scale in 0.1 M -hydroxyisobutyric acid (-HIB) solution using newly developed flow electrolytic column chromatography. It is found that the most stable No $^{2+}$ is oxidized to No $^{3+}$ within 3 min and that the oxidized No complex with -HIB holds the trivalent state in the column above the applied potential of 1.0 V.
