Periodiek systeem

Een overgangsmetaal is een element uit het D-blok van het periodiek systeem der elementen. Men onderscheidt

de 4d-overgangsmetalen van scandium tot zink
de 5d-overgangsmetalen van yttrium tot cadmium
de 6d-overgangsmetalen van lanthaan (of beter:lutetium) tot kwik
de 7d-overgangsmetalen van Rutherfordium tot Ununbium

De overgangsmetalen zijn:

21 Sc	22 Ti	23 V	24 Cr	25 Mn	26 Fe	27 Co	28 Ni	29 Cu	30 Zn
39 Y	40 Zr	41 Nb	42 Mo	(43) Tc	44 Ru	45 Rh	46 Pd	47 Ag	48 Cd
	72 Hf	73 Ta	74 W	75 Re	76 Os	77 Ir	78 Pt	79 Au	80 Hg
	(104) Rf	(105) Db	(106) Sg	(107) Bh	(108) Hs	(109) Mt	(110) Ds	(111) Rg	(112) Uub
