Answer
The following are properties of most d-transition elements:
(1) All are metals.
(2) Most are harder, more brittle, and have higher melting points and boiling points and higher heats of vaporization than nontransition metals.
(3) Their ions and compounds are usually colored.
(4) They form many complex ions.
(5) With few exceptions, they exhibit multiple oxidation states.
(6) Many of the metals and their compounds are paramagnetic.
(7) Many of the metals and their compounds are effective catalysts.
