  We present an X-ray spectral analysis of four solar analogs with different
ages and magnetic activity levels. We find largely different coronal
compositions. The most active stars tend to show an ``Inverse First Ionization
Potential'' (IFIP) effect, i.e., elements with low FIP are underabundant. Less
active stars tend to the opposite effect, with relative overabundances of
low-FIP elements. Equivalent Chandra results are presented that support these
results.
