Elementary processes for formation and decay of molecular negative ions in the gas phase have been discussed in relation to their importance in gaseous plasmas. The negative ion formation through (1) electron attachment, (2) ion pair formation, and (3) charge exchange has been described. Characteristics and mechanism of dissociative electron attachment as well as nondissociative electron attachment have been extensively discussed. Recent development has been reviewed on several specific processes associated with electron attachment, including electron attachment to vibrationally and electronically excited states, radicals, van der Waals molecules, and clusters. Also discussed are electron transfer from high-Rydberg atoms and alkali metal atoms to electron-attaching molecules. For processes responsible for decay of negative ions, the ion-molecule reactions including electron detachment and the ion-ion recombination (mutual neutrallization) have been briefly discussed.
