118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).
Ligands may bridge two or more centres. The prefix μ is used to specify a bridging ligand in both the formula and the name. For example the dimeric form of aluminium trichloride: Al 2 Cl 4 (μ-Cl) 2 di-μ-chlorido-tetrachlorido-1κ 2 Cl,2κ 2 Cl-dialuminium. This example illustrates the ordering of bridging and non bridging ligands of the same ...
