The cation is always named first. Ions can be metals, non-metals or polyatomic ions. Therefore, the name of the metal or positive polyatomic ion is followed by the name of the non-metal or negative polyatomic ion. The positive ion retains its element name whereas for a single non-metal anion the ending is changed to -ide.
Polyatomic cations of the same element are named as the element name preceded by di-, tri-, etc., e.g.: Hg 2+ 2 dimercury(2+) Polyatomic cations made up of different elements are named either substitutively or additively, e.g.: PH + 4 phosphanium; SbF + 4 tetrafluorostibanium (substitutive) or tetrafluoridoantimony(1+)
Some ionic compounds contain polyatomic ions, which are charged entities containing two or more covalently bonded types of atoms. It is important to know the names of common polyatomic ions; these include: ammonium (NH + 4) nitrite (NO − 2) nitrate (NO − 3) sulfite (SO 2− 3) sulfate (SO 2− 4) hydrogen sulfate (bisulfate) (HSO − 4 ...
The term molecule may or may not be used to refer to a polyatomic ion, depending on the definition used. The prefix poly-carries the meaning "many" in Greek, but even ions of two atoms are commonly described as polyatomic. [2] In older literature, a polyatomic ion may instead be referred to as a radical (or less commonly, as a radical group).
IUPAC nomenclature is used for the naming of chemical compounds, based on their chemical composition and their structure. [1] For example, one can deduce that 1-chloropropane has a Chlorine atom on the first carbon in the 3-carbon propane chain.
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
It is a polyatomic anion with the chemical formula H C O − 3. Bicarbonate serves a crucial biochemical role in the physiological pH buffering system. [3] The term "bicarbonate" was coined in 1814 by the English chemist William Hyde Wollaston. [4] [5] The name lives on as a trivial name.
In chemistry, an aluminate is a compound containing an oxyanion of aluminium, such as sodium aluminate. In the naming of inorganic compounds, it is a suffix that indicates a polyatomic anion with a central aluminium atom. [1]
