Size of atomic nucleus is wrong[edit]
The atomic nucleus article clearly states that "The diameter of the nucleus is in the range of 1.7566 fm (1.7566×10−15 m) for hydrogen (the diameter of a single proton) to about 11.7142 fm for uranium" which means the image has the wrong size (10-12 m). That's two or three order of magnitude larger than the real size of a nucleus. - Assaiki (talk) 18:11, 15 August 2021 (UTC)
