Diamagnetism is a property exhibited by all substances, including atoms and molecules, due to the presence of electrons in their atomic or molecular orbitals. Diamagnetic substances have all their electrons paired up in their orbitals, resulting in a cancellation of magnetic moments. As a result, diamagnetic substances are weakly repelled by an external magnetic field.…

Paramagnetism is a property exhibited by certain substances that contain unpaired electrons in their atomic or molecular orbitals. These unpaired electrons create magnetic moments that align with an external magnetic field, causing the substance to be weakly attracted into the field. In other words, paramagnetic substances become weakly magnetized in the presence of an external…

Crystal Field Theory (CFT) is a theoretical model used in coordination chemistry to describe the electronic structure and properties of coordination complexes. It focuses on the interaction between the ligands and the metal’s d orbitals, considering the electrostatic effects of the ligands’ negative charges on the metal center. CFT provides a simplified explanation of how…

Ligand Field Theory (LFT) is a theoretical model used in coordination chemistry to explain the electronic structure and properties of coordination complexes. It provides insights into how the arrangement of ligands around a central metal atom or ion affects the energies of the metal’s d orbitals, which in turn influences the complex’s color, magnetic properties,…

Naming ligands in coordination compounds follows a systematic set of rules established by the International Union of Pure and Applied Chemistry (IUPAC). The goal is to provide a clear and consistent way of naming compounds that accurately reflects their composition. The name of the ligand comes before the name of the central metal atom or…

Chelating ligands are a specific type of polydentate ligands that have multiple coordinating atoms or groups capable of forming multiple bonds with a central metal atom or ion in a coordination complex. The term “chelate” comes from the Greek word “chele,” meaning “claw,” which illustrates how these ligands wrap around the metal atom like a…

Polydentate ligands, also known as chelating ligands, are molecules or ions that can form multiple coordinate covalent bonds with a central metal atom or ion in a coordination complex. These ligands have multiple atoms or groups with available lone pairs of electrons, which allows them to form multiple bonds to the metal center. The term…

Bidentate ligands are molecules or ions that have the ability to form two separate coordinate covalent bonds with a central metal atom or ion in a coordination complex. These ligands contain two atoms or groups that can each donate a lone pair of electrons to the metal, forming two bonds. Bidentate ligands play a significant…

Monodentate ligands are molecules or ions that can form a single coordinate covalent bond with a central metal atom or ion in a coordination complex. These ligands typically donate one pair of electrons to the metal center, forming a single bond. Monodentate ligands are important components in the formation of coordination compounds and play a…

A covalent bond is a type of chemical bond that involves the sharing of electron pairs between atoms. It is one of the fundamental ways atoms can combine to form molecules. Covalent bonds typically occur between non-metal atoms, allowing them to achieve a more stable electron configuration similar to that of noble gases. Here are…
