Most galaxies in the present-day Universe are in groups and poor clusters. Groups are the building blocks from which clusters form, and they accordingly occupy an important niche in the continuum between isolated galaxies and rich clusters. We here propose to exploit the high X-ray brightnesses and relative sparseness of four compact groups from the Hickson catalog for which we do not yet have the necessary high angular resolution X-ray data to: examine the metallicity distribution of the intragroup gas; test for association between abundance variations and individual galaxies; and examine the X-ray morphology of the groups to understand regulation of cooling flows and interaction with radio sources -- at a level of detail not possible prior to the availability of Chandra data.
