| caption = An illustration of the [[Chemistry:Helium|helium]] atom, depicting the [[Physics:Atomic nucleus|nucleus]] (pink) and the [[electron cloud]] distribution (black). The nucleus (upper right) in helium-4 is in reality spherically symmetric and closely resembles the electron cloud, although for more complicated nuclei this is not always the case. The black bar is one [[Angstrom|angstrom]] ({{val|e=-10|u=m}} or {{val|100|ul=pm}}).
