Why is "No" atmosphere penetration indicated for ultraviolet wavelength? If you've ever been sunburnt, you're familiar with the atmospheric penetrative power of UV. So Y. — Preceding unsigned comment was added by 85.148.194.103 (talk) 08:51, 15 April 2020 (UTC)

Size of atomic nucleus is wrong

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)
