Exploration of Transition Metals: Properties, Uses, and Biological Significance

This comprehensive overview delves into the fascinating world of transition metals, specifically focusing on groups 9 to 12. Discover the unique applications of cobalt in blue glass and cancer treatment through Co-60. Learn about nickel in rechargeable batteries, platinum in jewelry and catalysis, and silver’s unmatched electrical conductivity. We’ll also explore the catalytic properties of palladium, the toxic nature of cadmium, and the historical significance of gold. Each metal’s diverse roles in technology, biology, and industry highlight their importance in both everyday life and advanced applications.
