Chemical property 147027 224510938 2008-07-09T04:44:48Z Adluolas 1110219 /* See also */ A '''chemical property''' is any of a material's properties that becomes evident during a [[chemical reaction]]; that is, any quality that can be established only by changing a substance's [[Chemical substance|chemical identity]]. Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's [[Chemical structure|internal structure]] must be affected for its chemical properties to be investigated. Chemical properties can be contrasted with [[physical properties]], which can be discerned without changing the substance's structure. However, for many properties within the scope of [[physical chemistry]] (and other disciplines at the border of chemistry and physics), the distinction may be a matter of researcher's [[Perspective (cognitive)|perspective]]. [[Material properties]] (both physical and chemical) can be viewed as [[supervenient]]; i.e., secondary to the underlying reality. Several layers of superveniency are possible. Chemical properties can be used for building [[chemical classification]]s. ==Examples of chemical properties== * [[Electronegativity]] * [[Ionization potential]] * [[pH balance]] * [[Reactivity]] against other [[chemical substance]]s * [[Heat of combustion]] * [[Enthalpy of formation]] * [[Toxicity]] * [[Chemical stability]] in a given environment * [[Flammability]] * Preferred [[oxidation state]](s) * [[Coordination number]] * Capability to undergo a certain set of transformations e.g. molecular [[dissociation (chemistry)|dissociation]], chemical [[combination]], [[reduction (chemistry)|redox]] reactions under certain physical conditions in the presence of another [[chemical substance]] * Preferred types of [[chemical bond|bonds]] to form e.g., [[metallic]], [[ion|ionic]], [[covalent]] == See also == {{Portal|Chemistry|Nuvola apps edu science.png}} * [[Physical property]] * [[Chemical structure]] * [[Material properties]] * [[Biological activity]] * [[QSAR]], quantitative structure-affinity relationship * [[Lipinski's Rule of Five]], describing molecular properties of drugs [[Category:Chemistry]] [[Category:Chemical properties|*]] [[ar:خاصية كيميائية]] [[de:Stoffeigenschaft]] [[el:Χημική ιδιότητα]] [[es:Propiedades químicas]] [[id:Sifat kimia]] [[pt:Propriedade química]] [[simple:Chemical property]] [[th:สมบัติทางเคมี]] [[zh:化学性质]]
