Transition Metal

The transition metals make up the bulk of the middle of the periodic table. When you think of the word "metal" one of these elements probably comes to mind.  They are usually malleable, conductive, ductile, and have high melting temperature. They are less reactive than the Alkali and Alkaline Earth metals. 

There are generally considered to be about 38 transition metals.
