Recent studies on the adsorption of common gases on various single crystal planes of tungsten are reviewed. First, being of great importance, preparation and characterization of well-defined solid surfaces briefly was discussed. One of the promising experiment for under-standing of the fundamental process of adsorption would be the use of the single crystal sur-faces of tungsten which easily get clean. The measurement of the surface potential of some common gases on such planes extensively has been carried out with good accuracy by the author. So far, there are some arguments on whether the adsorbate would be atomic or mo-lecular, when diatomic molecules are adsorbed on tungsten. In particuar, hydrogen or nitrogen on W(100), and β-CO/W, being quite interesting but still unsettled, were discussed with the results of the surface potential measurement, flash desorption, LEED observation and new in-formations from FES and UPS in available.
