Thorium, electrochemistry

A full discussion of thorium electrochemistry is available (3). Thorium is generally more acidic than the lanthanides but less acidic than other light actinides, such as U, Np, and Pu, as expected from the larger Th" " ionic radius (108 pm). 

The electrochemistry of the uranium(lV) and thorium(IV) complexes M(acac)2L (L = Pc, oep dianions) has been studied in benzonitrile solution. In the complexes of both elements, a series of reversible redox processes have been detected, most of which are centred on the macrocyclic rings (Table 21). 

Berzelius, J6n Jacob (1779-1848) Swedish chemist. After moving to Stockholm he worked with mining chemists and, with them, discovered several elements, including cerium (1803), selenium (1817), lithium (1818), thorium (1828), and vanadium (1830). He also worked on atomic weights and electrochemistry and devised the current notation for chemical elements. 

Berzelius, Baron Jons Jacob (1779 1848) A Swedish chemist who discovered several elements including cerium, selenium, lithium, thorium, and vanadium. He invented the present notation of chemical elements and electrochemistry, and worlmd on the atomic weights of many substances.
