Definition
Transition metals are a unique group of elements that share distinct properties and characteristics, making them essential in both chemistry and various practical applications.
Located in the d-block of the periodic table, transition metals consist of elements that have partially filled d orbitals. This group includes well-known elements such as iron, copper, and nickel, among others.
What sets transition metals apart from other metal groups is their ability to form multiple oxidation states. This means they can lose different numbers of electrons during chemical reactions, leading to a variety of chemical behaviors and the formation of a myriad of compounds.
Electronic Configuration
The general electronic configuration of d-Block elements is
[Noble gas] (n-1)d1-10ns1-2
For 3d series
[Ar] 3d1-10 4s1-2 (Scandium to Zinc)
Exceptional Configurations:
Cr: [Ar] 3d5 4s1
Cu: [Ar] 3d10 4s1
For 4d transition series
[Kr] 4d 1-10 5s1-2 (Ytterbium to Cadmium)
Exceptional Configurations:
Nb: [Kr] 4d4 5s1
Mo: [Kr] 4d5 5s1
Tc: [Kr] 4d6 5s1
Ru: [Kr] 4d7 5s1
Rh: [kr] 4d8 5s1
Pd: [Kr] 4d10 5s0
Ag: [Kr] 4d10 5s1
Why are Zinc, Cadmium and Mercury not regarded as transition metals?
Notice an intriguing aspect of the periodic table: zinc (Zn), cadmium (Cd), and mercury (Hg) are often excluded from the category of transition metals.
While they are located within the d block, their classification is rooted in their unique electron configurations and chemical properties. Transition metals are defined by their ability to form variable oxidation states and to create colored compounds, a behavior closely associated with the presence of unpaired d electrons.
However, zinc, cadmium, and mercury display a full complement of d electrons in their outer shells, making them distinct from their transition metal counterparts.
For instance, zinc has an electron configuration of [Ar] 3d10 4s2. In this configuration, all ten d electrons are paired, resulting in no variable oxidation states, as zinc typically exhibits a +2 oxidation state.
This pattern continues for cadmium and mercury, both of which maintain a completely filled d subshell, which inhibits the characteristic attributes of traditional transition metals.
Additionally, another key characteristic of transition metals is their ability to form complex ions with variable coordination numbers. Zinc, cadmium, and mercury typically form simple ions rather than complex ones and often do not exhibit the colorful compounds associated with transition metals.
Furthermore, due to the stability and filled nature of their d orbitals, these elements generally exhibit less reactivity compared to their transition metal neighbors.
In conclusion, understanding d block electron configuration charts is essential for anyone looking to grasp the intricacies of chemistry and atomic structure.
