Nombre for Ionic Compounds
Ionic compounds include cations (positive ions) and anions (negative ions). The nomenclature, or perhaps naming, of ionic compounds is based on what they are called of the element ions. Listed below are the principal naming conventions to get ionic ingredients, along with examples to show how they are being used: Roman NumeralsA Roman numeral in parentheses, followed by the name of the element, is employed for factors that can type more than one great ion. Normally, this is seen with metals. You may use a chart to see the conceivable valences intended for the components. Fe2+ Iron (II)Fe3+ Iron (III)Cu+ Copper (I)Cu2+ Copper (II) -ous and -icAlthough Roman numerals are used to represent the ionic charge of cations, it can be still common to see and use the endings -ous or -ic. These endings are put into the Latina name with the element (e. g., stannous/stannic for tin) to represent the ions with smaller or higher charge, respectively. The Both roman numeral identifying convention has wider appeal because many ions have more than two valences. Fe2+ FerrousFe3+ FerricCu+ CuprousCu2+ Cupric
-ideThe -ide ending is added to the name of any monoatomic ion of an element. H- HydrideF- FluorideO2- OxideS2- SulfideN3- NitrideP3- Phosphide -ite and -ateSome polyatomic anions contain fresh air. These anions are called oxyanions. When an element forms two oxyanions, the one with significantly less oxygen is given a identity ending in -ite and the one with an increase of oxgyen has a term that ends in -ate. NO2- NitriteNO3- NitrateSO32- SulfiteSO42- Sulfate
hypo- and per-In the case where there is a series of four oxyanions, the hypo- and per- prefixes are being used in conjunction with the -ite and -ate suffixes. The hypo- and per- prefixes indicate less o2 and more air, respectively. ClO- HypochloriteClO2- ChloriteClO3- ChlorateClO4- Perchlorate bi- and di- hydrogenPolyatomic anions occasionally gain a number of H+ ions to form anions of the lower fee. These ions are named by adding the word hydrogen or dihydrogen in front with the name...
