Iron(II) chloride, also known as ferrous chloride, is the chemical compound of formula FeCl 2.It is a paramagnetic solid with a high melting point. The compound is white, but typical samples are often off-white.
Many other names have been used for this set, and its borders are not agreed on. Precious metals – Variously-defined group of non-radioactive metals of high economical value. Superactinides – Hypothetical series of elements 121 to 157, which includes a predicted "g-block" of the periodic table.
For example, "ferrous sulfide" can refer to the 1:1 species (mineral name troilite) or a host of Fe-deficient derivatives . The mineral magnetite ("lode stone") is a mixed-valence compound with both Fe(II) and Fe(III), Fe 3 O 4 .
Chemical nomenclature is a set of rules to generate systematic names for chemical compounds.The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC).
Once this name and symbol is proposed, there is still a comment period before they become official and replace the systematic name and symbol. At the time the systematic names were recommended (1978), names had already been officially given to all elements up to atomic number 103, lawrencium. While systematic names were given for elements 101 ...
Although most compounds are referred to by their IUPAC systematic names (following IUPAC nomenclature), ...
The main structure of chemical names according to IUPAC nomenclature. The International Union of Pure and Applied Chemistry (IUPAC) has published four sets of rules to standardize chemical nomenclature. There are two main areas: IUPAC nomenclature of inorganic chemistry (Red Book) IUPAC nomenclature of organic chemistry (Blue Book)
For isotopes of undiscovered elements, either systematic names (e.g. 296 Uue) or atomic numbers (e.g. 296 119) are acceptable for the symbols, but only the systematic names can be used for the full names (e.g. ununennium-296, not element 119-296 which nobody uses).
