Transition Metals (Periodic Table of the Elements)

Extra so than any of the opposite significant teams of components within the periodic desk, the transition metals have formed human historical past and feature been the workhorses of undefined. the invention of steel copper ended the Stone Age and ushered within the Bronze Age. Alloys of iron (especially metal) later took over, and the Iron Age changed the Bronze Age.
