ydinteiden

Ydinteiden is the genitive plural form of the Finnish noun ydin, meaning nucleus. It is used primarily in scientific Finnish to refer to multiple atomic nuclei and to express possession or association in phrases discussing properties or processes that involve more than one nucleus. In physics and chemistry texts, ydinteiden is encountered in contexts such as energy levels, binding energies, nuclear reactions, and isotopic analyses, where statements about “the nuclei” or “of the nuclei” are needed. For example, phrases like ydinteiden energiatason (the energy levels of the nuclei) or ydinteiden koostumus (the composition of the nuclei) illustrate its typical usage.

The term is distinct from biological terminology for cell nuclei, since Finnish usually uses tuma to denote a cell nucleus rather than ydinteiden. Thus, ydinteiden remains a term anchored in physics and chemistry rather than biology. The form reflects Finnish noun inflection, with the genitive plural indicating a relationship of possession or association to the nouns involved.

In summary, ydinteiden is a specialized plural genitive form used when discussing more than one atomic nucleus in scientific literature, serving to denote either possession or relevance to the nuclei in question. It is not a general-purpose term outside the physical sciences, and its usage is largely confined to contexts involving atomic structure, nuclear phenomena, or isotopic studies.
