Many transition metals cannot lose enough electrons to attain a noble-gas electron configuration. The metallic elements in the periodic table located between the transition metals and the weakly nonmetallic metalloids have received many names in the literature, such as post-transition metals, poor metals, other metals, p-block metals and chemically weak metals; none have been recommended by IUPAC.The most common name, post-transition metals, is generally used in this article. Transition metals and their compounds function as catalysts either because of their ability to change oxidation state or, in the case of the metals, to adsorb other substances on to their surface and activate them in the process. The alkaline earth metals, beginning with beryllium are to the left and the boron group elements are to the right. Transition metals are defined as those elements that have (or readily form) partially filled d orbitals. A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals.On the basis of this definition, scandium and zinc do not count as transition metals - even though they are members of the d block.. Scandium has the electronic structure [Ar] 3d 1 4s 2.When it forms ions, it always loses the 3 outer electrons and ends up with an argon structure. Transition metals are like main group metals in many ways: They look like metals, they are malleable and ductile, they conduct heat and electricity, and they form positive ions. These metals tend to be very hard. Chemists often use something called a "d electron count" instead of valence electrons to describe transition elements. Aluminum’s abundance percentage is more as it is found in more than 260 minerals. Tobin, Declan. Because of these unique qualities, these metals are often used in industry as catalysts for various chemical reactions.
