原子中质量集中、由质子和中子组成的带正电荷的核心
The atomic nucleus is the tiny, dense core at the center of an atom made up of protons and neutrons held tightly together. It matters because the nucleus contains nearly all of an atom's mass and determines what element the atom is, making it fundamental to understanding how matter is structured and behaves.

原子核（德语：Atomkern，英语：Atomic nucleus）是原子的组成部分，位于原子的中央，占有原子的大部分质量。組成原子核的有中子和質子。当周围有和其中质子等量的电子围绕时，构成的是原子。原子核極其渺小，比如鈾的的原子半徑/原子核半徑比例是26634，而氫是60250。
