In chemistry, the chemical around is the application of the mathematical concept to an atom or part of it or a molecule or part of it, or the "point" we are considering.
For this reason, as in mathematics, the extent of the surrounding is not unambiguous and varies from time to time depending on how close the environment is to the extent that we are considering influencing in a "not negligible way".
In most cases, the chemical environment is reduced to directly interacting atoms or molecules with our point, through chemical bonds, weak interactions, crystalline structures, and so on. but may also be more extensive.
In the case of solid samples it is usually important to consider the crystalline lattice or the supramolecular structure, in the case of solutions the interaction of the solvent, in the case of gas phases (in the range of ideality) around it is of importance much less. However, these are general rules and are not applicable in all cases since the circle is based on the chosen mathematical model and the effect studied, and can be, for example, represented only by energy levels orbital close to that of the ' electron I excited to do spectroscopic measurements.
The chemical around it causes changes in the chemical and physical properties of chemical compounds by generating chemical displacement. Voices correlateemodify wikitesto
