Transition Elements (2802)
Transition elements are located in the d-block of the periodic table, spanning groups 3 to 12. They are distinguished by their partially filled d orbitals in atoms or ions, the ability to exhibit multiple oxidation states, and diverse chemical reactivity. These elements are crucial in various chemical reactions and physical processes, with significant roles in catalysis, alloy formation, coloration, and electron transfer, among other applications.
