TRANSITION ELEMENTS Meaning and
Definition
-
Transition elements, also known as transition metals, refer to a group of chemical elements that occupy the middle section of the periodic table. These elements are characterized by having partially filled d or f orbitals in their outermost energy levels. The transition elements include the elements from groups 3 to 12 on the periodic table, which includes elements such as iron, copper, zinc, and gold.
Transition elements possess several unique physical and chemical properties that distinguish them from other elements. One of their defining features is their ability to exhibit multiple oxidation states, which enables them to form various types of compounds. Additionally, these elements tend to be good conductors of heat and electricity due to the presence of free electrons in their d orbitals. Many transition elements are also known for their high melting and boiling points, as well as their notable density.
The transition elements often display good catalytic activity, meaning that they can facilitate chemical reactions without being consumed themselves. This property makes them valuable in industrial processes and in biological systems. Furthermore, many of these elements exhibit vibrant and intense colors, which makes them useful in pigments and dyes.
Overall, transition elements play a vital role in various fields such as chemistry, physics, and engineering. Their unique properties and versatility make them important building blocks to develop materials, manufacture electronics, and study the behavior of substances under differing conditions.

Etymology of TRANSITION ELEMENTS
The term transition elements comes from the concept of a chemical transition that these elements undergo. In chemistry, a transition refers to the movement of an electron from one energy level to another within an atom. The name transition elements emphasizes the fact that these elements have partially filled d orbitals, which allow for the transition of electrons between energy levels. These elements are also known as transition metals due to their metallic properties. The term transition in this context is derived from the Latin word transire, meaning to go across or to pass through.
