Summary
A depiction of the atomic structure of the <a href="https://en.wikipedia.org/wiki/helium" class="extiw" title="w:helium">helium</a> atom. The darkness of the <a href="https://en.wikipedia.org/wiki/electron" class="extiw" title="w:electron">electron</a> <a href="https://en.wikipedia.org/wiki/electron_cloud" class="extiw" title="w:electron cloud">cloud</a> corresponds to the line-of-sight integral over the <a href="https://en.wikipedia.org/wiki/probability_function" class="extiw" title="w:probability function">probability function</a> of the 1s <a href="https://en.wikipedia.org/wiki/atomic_orbital" class="extiw" title="w:atomic orbital">atomic orbital</a> of the electron. The magnified <a href="https://en.wikipedia.org/wiki/atomic_nucleus" class="extiw" title="w:atomic nucleus">nucleus</a> is schematic, showing <a href="https://en.wikipedia.org/wiki/proton" class="extiw" title="w:proton">protons</a> in pink and <a href="https://en.wikipedia.org/wiki/neutron" class="extiw" title="w:neutron">neutrons</a> in purple. In reality, the nucleus (and the wavefunction of each of the <a href="https://en.wikipedia.org/wiki/nucleon" class="extiw" title="w:nucleon">nucleons</a>) 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.)
