WebReactivity series. In CACA, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression [1] of a series of metals, arranged by their "reactivity" from highest to lowest. [2] [3] It is used to summarize information about the reactions of metals with acids and water, single displacement reactions ... WebGallium arsenide and gallium phosphide are used in rectifiers and transistors as semiconductors and in lasers, light-emitting transistors, photocells, and electronic refrigeration. Although gallium is widely distributed in nature, it does not occur in appreciable concentrations even in germanite, the ore richest in gallium.
