Atomtörzs
Atomtörzs is a term used in certain theoretical physics contexts, particularly within some older or specialized models of atomic structure. It refers to the central part of an atom, encompassing the nucleus and any electrons that are tightly bound to it, often considered to be in inner electron shells. This concept is often contrasted with the valence electrons, which are the outermost electrons involved in chemical bonding. The idea of an atomtörzs helps to distinguish between the stable, core structure of an atom and its reactive outer shell. In modern quantum mechanics, the concept of distinct "shells" and a unified "core" is more nuanced, with electron orbitals and energy levels providing a more precise description. However, the atomtörzs model can still be useful for conceptualizing atomic behavior, especially when discussing ionization energies or the transition of electrons between energy levels. The term itself, likely of Germanic origin, emphasizes the "trunk" or "body" of the atom, suggesting its fundamental and stable nature. It is not a universally adopted or mainstream term in contemporary physics literature but appears in discussions of historical atomic models or specific theoretical frameworks.
