molekyynin
Molekyylin is a Finnish-language term that translates to "molecule" in English. A molecule is the smallest fundamental unit of a chemical compound that can exist independently and retain all the chemical and physical properties of that compound. It consists of two or more atoms held together by chemical bonds. These atoms can be of the same element, as in the case of oxygen (O2), or of different elements, as in the case of water (H2O). The specific arrangement of atoms within a molecule, known as its molecular structure, dictates the molecule's properties. For example, water molecules have a bent structure, which contributes to water's ability to dissolve many substances. Molecules are the building blocks of all matter and are essential for life as we know it. Understanding the structure and behavior of molecules is a fundamental aspect of chemistry. The size of molecules varies greatly, from simple diatomic molecules like hydrogen (H2) to complex macromolecules like DNA.
