["According to the disintegration theory of Rutherford and Soddy," writes Sir Edward Thorpe, History of Chemistry, vol 2, p. 42, "the radio-active elements are forms of matter undergoing changes resulting in the formation of new forms possessing chemical and physical properties differing from those of the parent substance.
(the radio-active elements; are undergoing; changes resulting in the formation of new forms) (changes; resulting; in the formation of new forms) (new forms; possessing; chemical and physical properties)
the radio-active elements changes new forms
are undergoing resulting possessing
changes resulting in the formation of new forms
