### Delta x

Can anyone explain why the diameter of an atom is typically used for Delta x in the equation? Also, are there any other values that can be used?

I think it has something to do with the particle in the box analogy, like the electron has to be found somewhere inside this diameter which is the box. I'm not sure though.

I am aware that they use the diameter because the electron is typically found outside of the diameter. In problems I have done I have noticed that the diameter was used to compare to the range of x values after solving the equation. Kind of a way to show that the electrons range even outside of the diameter.
