  2. Nobelium - Wikipedia

    en.wikipedia.org/wiki/Nobelium

    In 1994, as part of an attempted resolution to the element naming controversy, IUPAC ratified names for elements 101–109. For element 102, it ratified the name nobelium (No) on the basis that it had become entrenched in the literature over the course of 30 years and that Alfred Nobel should be commemorated in this fashion.

    To avoid long and tedious names in normal communication, the official IUPAC naming recommendations are not always followed in practice, except when it is necessary to give an unambiguous and absolute definition to a compound. IUPAC names can sometimes be simpler than older names, as with ethanol, instead of ethyl alcohol. For relatively simple ...

    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)

    en.wikipedia.org/wiki/Nitric_oxide

    Nitric oxide (nitrogen oxide or nitrogen monoxide [1]) is a colorless gas with the formula NO. It is one of the principal oxides of nitrogen . Nitric oxide is a free radical : it has an unpaired electron , which is sometimes denoted by a dot in its chemical formula ( • N=O or • NO).

    en.wikipedia.org/wiki/Chemical_nomenclature

    IUPAC Nomenclature ensures that each compound (and its various isomers) have only one formally accepted name known as the systematic IUPAC name. However, some compounds may have alternative names that are also accepted, known as the preferred IUPAC name which is generally taken from the common name of that compound. Preferably, the name should ...

    Basic IUPAC inorganic nomenclature has two main parts: the cation and the anion. The cation is the name for the positively charged ion and the anion is the name for the negatively charged ion. [13] An example of IUPAC nomenclature of inorganic chemistry is potassium chlorate (KClO 3): Potassium chlorate "Potassium" is the cation name.

  8. Nitroxyl - Wikipedia

    en.wikipedia.org/wiki/Nitroxyl

    Nitroxyl (common name) or azanone (IUPAC name) [2] is the chemical compound HNO. It is well known in the gas phase. [3] [4] Nitroxyl can be formed as a short-lived intermediate in the solution phase. The conjugate base, NO −, nitroxide anion, is the reduced form of nitric oxide (NO) and is isoelectronic with dioxygen. The bond dissociation ...
