Lec-37-Chap22-1-Complete 12/4/2009 Transition Metal Chemistry 3 Properties of Transition ( d -block) elements Transition ( d -block) elements occupy the central part of the periodic table, from periods 4 to 7. Their properties are intermediate between the s -block metals (very reactive) and the p -block metals (less reactive) . They present a steady progression in properties from those of the s -block to those of the p -block. 5 Properties of Transition ( d -block) elements metals (conduct electricity). ductile and malleable (wires and sheets) silvery or bluish (not Au and Cu) high melting and boiling temperatures (not Hg) high densities (up to 20 g cm –3 ) many form brightly-colored compounds some are paramagnetic, a few are ferromagnetic they form complex ions most have multiple oxidation states (except Zn 2+ , Sc 3+ ) 6
