Popis:	The kinetics of the early stages of oxidation of freshly generated iron surfaces in aqueous solutions are presented. The results show that at potentials below the Fe/Fe(II) reversible potential, iron oxidizes by random oxidation of exposed metal atoms to produce a monolayer of adsorbed FeOH. At potentials above the Fe/Fe(II) reversible potential, formation of the first monolayer of Fe(II) oxide also occurs by random oxidation of exposed metal atoms. There is no evidence for separate nucleation and two-dimensional growth steps participating in these mechanisms.
