However, a catalytic property would also be a chemical property. 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 boundary between chemistry and physics, the ...
A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample being observed is large or small. Thus, conversely, if the property of a substance changes as the sample size changes, that property is not a characteristic ...
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
More generally properties can be combined to give new properties, which may be called derived or composite properties. For example, the base quantities [11] mass and volume can be combined to give the derived quantity [12] density. These composite properties can sometimes also be classified as intensive or extensive.
Some chemical substances can be combined or converted into new substances by means of chemical reactions. Chemicals that do not possess this ability are said to be inert. Pure water is an example of a chemical substance, with a constant composition of two hydrogen atoms bonded to a single oxygen atom (i.e. H 2 O).
The chemical identity of the ions added is also important in many uses. For example, fluoride containing compounds are dissolved to supply fluoride ions for water fluoridation. [88] Solid salts have long been used as paint pigments, and are resistant to organic solvents, but are sensitive to acidity or basicity. [89]

The depth of analysis depends on the field of study or the chemical and physical properties of interest. The English word "isomer" ( / ˈ aɪ s əm ər / ) is a back-formation from "isomeric", [ 2 ] which was borrowed through German isomerisch [ 3 ] from Swedish isomerisk ; which in turn was coined from Greek ἰσόμερoς isómeros , with ...
