Chelation (/ kiːˈleɪʃən /) is a type of bonding of ions and their molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central metal atom. [1][2] These ligands are called chelants, chelators, chelating agents, or sequestering agents.

: to combine with (a metal) so as to form a chelate ring. : to react so as to form a chelate ring. : a compound having a ring structure that usually contains a metal ion held by coordinate bonds. …

5 days ago · chelate, any of a class of coordination or complex compounds consisting of a central metal atom attached to a large molecule, called a ligand, in a cyclic or ring structure.

Jul 3, 2019 · A chelate is an organic compound formed when a polydentate ligand bonds to a central metal atom. Chelation, according to the IUPAC, involves the formation of two or more …

A metal ion in solution does not exist in isolation, but in combination with ligands (such as solvent molecules or simple ions) or chelating groups, giving rise to complex ions or coordination compounds. These complexes contain a central atom or ion, often a transition metal, and a cluster of ions or neutral molecules surrounding it.

CHELATE definition: 1. a chemical compound in which a substance is joined to a metal atom by two or more bonds…. Learn more.

Let us discuss the chelate meaning, a chelate is a compound that has two or more coordinate or dative bonds between a ligand (usually organic) and a central metal atom.

Thus, chelation may be defined as an equilibrium reaction between a metal ion and a complexing agent, characterized by the formation of more than one bond between the metal and a molecule of the complexing agent and resulting in the formation of a …

sts (enzymes) are chelates. In addition to their significance in living organisms, chelates are also economically important, both as products in themselves and as agents in the pr. duction of other chemicals. A chelate is a chemical compound composed of a meta.

Chelation is a process in which a polydentate ligand bonds to a metal ion, forming a ring. The complex produced by this process is called a chelate, and the polydentate ligand is referred to as a chelating agent.
