atomijärjestys
Atomijärjestys refers to the order of atoms within a molecule or crystal structure. This arrangement is crucial as it dictates the molecule's physical and chemical properties. In organic chemistry, atomijärjestys is often represented by structural formulas, which show how atoms are connected by chemical bonds. For example, the difference between ethanol and dimethyl ether, both with the molecular formula C2H6O, lies solely in their atomijärjestys, leading to vastly different properties. Ethanol has an -OH group, making it an alcohol, while dimethyl ether has an ether linkage.
In solid-state physics and crystallography, atomijärjestys describes the precise spatial arrangement of atoms in a crystalline
