The helium atom, the smallest of atoms, has a nucleus (pink) consisting of two protons (red) and two neutrons (purple). The fuzzy cloud is the electron probability cloud, with darker regions of the cloud indicating where the electron most likely is.

Summary

[edit]
Description
Afrikaans: 'n Uitbeelding van die atoomstruktuur van die heliumatoom. Een femtometer (wit stafie) word teenoor die atoomkern aangedui, en een ångströmlengte (swart stafie) teenoor die hele atoom. Die donkerte van die elektronwolk stem met die siglyn-integraal oor die waarskynlikheidsfunksie van die elektron se 1s-atoomorbitaal ooreen. Die vergrote kern is skematies en toon protone in rooi en neutrone in pers. In werklikheid is die golffunksie van die kern soos elkeen van die nukleone ook sferies simmetries en 1s, en die vier deeltjies, elk met 'n ander kwantumgetal, sal soos die elektrone almal in dieselfde mees waarskynlike ruimte verkeer, naamlik in die presiese middelpunt van die kern. Vir meer komplekse kerne is dit egter nie die geval nie. Met dank aan Åke Back.
English: A depiction of the atomic structure of the helium atom. The darkness of the electron cloud corresponds to the line-of-sight integral over the probability function of the 1s atomic orbital of the electron. The magnified nucleus is schematic, showing protons in red and neutrons in purple. In reality, the nucleus (and the wavefunction of each of the nucleons) is also spherically symmetric and 1s, and the four particles, each with a different quantum number, like the electrons in the helium atom, are all most likely to be found in the same space, at the exact center of the nucleus. (For more complicated nuclei this is not the case. Thanks to Åke Back.)
