Qualitative estimates of the relative iron and oxygen ions (Fe/O) in flows of solar cosmic rays from impulsive and long-duration solar flares are obtained for different ion energy ranges. The Fe/O value serves as a measuring unit for the known FIP effect in the solar atmosphere. It is shown that the FIP effect is most evident (maximum Fe/O values) in impulsive events for ions at energies <2 MeV/n. In long-duration events, the Fe/O value gradually decreases in parallel with ion energy and its maximum values are observable in the area of relatively low energies. The comparison of some flare models provided grounds for a qualitative explanation of the Fe/O behavior in response to changes in ion energies for both classes of solar cosmic ray (SCR) events.
