complexes. The Au(I) configuration has the d10 configuration and is prone to the formation of linear structures. An important example is the cyanide complex [Au(CN)2]- which is one of the compounds involved in the gold extraction process from low grade ores. In addition the Au(-I) oxidation state (electronic confguration d10s2) is known and there are several examples of crystallographically characterised Au(-I) compounds such as [NMe4]Au. Gold is the most electronegative of the d-block metals and its

Briefly explain the internal process of plate tectonics and the external geological process of erosion. ● Continental Plates (Crust)- consists of the continental crust‚ and the oceanic crust ● Mantle- solid rock‚ but under its rigid outermost part is a zone of very hot‚ partly melted rock that flows like soft plastic. The plastic is asthenosphere. ● Core- is very hot and has a solid inner part‚ surrounded
