This concerns the process whereby new @I03183@ species are formed when gaseous molecules interact with ions. The process may involve transfer of an electron, @P04906@ or other charged species between the reactants. When a positive ion results from chemical @I03183@, the term may be used without qualification. When a negative ion is involved, the term negative ion chemical @I03183@ should be used; note that negative ion formation by @A00512@ of a free electron does not fall within this definition. Chemical @I03183@ and chemi-@I03183@ are two terms which should not be used interchangeably.
