Chapter 19: Transition Metals and Coordination Chemistry d-Block Elements and Their Compounds Transition metals, are located in groups 3 through 11. They are called transition metals because they transition between the highly reactive s block metals and the much less reactive metals of group 12 and the p block. 3

Chapter 19: Transition Metals and Coordination Chemistry d -Block Elements and Their Compounds 4 Note: The ordering of the ns and (n-1)d energy level shifts once the (n-1)d orbitals contain e - causing the (n-1)d e - to be lower in energy that the ns e - . Therefore , ns e - are lost before (n-1)d e - when forming transition metal ions. ns e - are also lost before (n-2)f e - .
