> Atoms exist on extremely tiny scales, just 1 ångström across... I may be misinterpreting, but it sounds like he's saying all atoms are 1 ångström in diameter

  That sounds within one or two orders of magnitude?
  • thayne 6y ago
    just one order of magnitude actually
    • saagarjha 6y ago
      One on each side, I guess.

  That's not a terrible place to start. "Under most definitions the radii of isolated neutral atoms range between 30 and 300 pm (trillionths of a meter), or between 0.3 and 3 ångströms." https://en.wikipedia.org/wiki/Atomic_radius https://en.wikipedia.org/wiki/Atomic_radius
