To help compare different orders of magnitude this page lists lengths between 10⁻¹¹ m and 10⁻¹⁰ m (10 pm and 100 pm).

Distances shorter than 10 pm

• 25 pm — empirical radius of hydrogen atom^[1]
• 28 pm — covalent radius of helium atom^[2]
• 31 pm — covalent radius of hydrogen atom^[1]
• 31 pm — calculated radius of helium atom^[2]
• 53 pm — calculated radius of hydrogen atom^[1]
• 80 pm — best resolution of a high-res EM

Distances longer than 100 pm
