Metals, through the emission of spectral lines, play a fundamental role in thecooling processes at work in the ICM. But when, where, and how these metalsformed and were distributed through the cluster volume is still under debate.Detailed measurements out to large radii will improve our knowledge of the metalenrichment in galaxy groups and clusters, by directly exploring most of thesystem.s volume. While in recent years metallicity measurements to R500 havebeen done for a sizable number of galaxy clusters, we are still missingsystematic measurements at such radii for galaxy groups. We re-propose a pilotsample of four galaxy groups that were awarded C time, one of which has nowbeen partially observed (IC1262), to derive the abundance profiles to R500.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
