absorbs a large amount of hydrogen, whichis given off again by gently heating the dry metal with a bunsenflarre, in Pd of Fig.VIII. When the cell contains a small amount ofhydrogen and a discharge passes from the alkali metal to the anodethe surface of the alkali metal assumes very intense colors,… … > FIG. VII. purple colors, while the caesium exhibits a greenish gray or bronzesurface. . VII. Caesium is distilled into the bulb at C when the electrodeA is raised, by means of a magnet, in order that no caesium vaporcondense upon the electrode. The diameter of the bulb is about5 cm., and the…
