Here's a more detailed breakdown:
* Hydrogen Atom Diameter: Approximately 106 picometers (pm).
* Hydrogen Nucleus (Proton) Diameter: Approximately 1 femtometer (fm).
To put this into perspective: Imagine a football field. If the nucleus were a marble in the center of the field, the entire atom would be the size of the whole field.
This vast difference in size highlights the fact that atoms are mostly empty space. The electrons orbiting the nucleus occupy a much larger volume than the nucleus itself.
