### Uncertainty concept

I am struggling to conceptualize the idea of using diameter as a delta X value... can someone explain how the diameter of something, for example an alveoli sac, is also equal to the uncertainty in position of something within that diameter?

### Re: Uncertainty concept

When diameter of a region is referred to in a Heisenberg uncertainty principle problem, the question is usually asking whether the electron is within that region (alveoli sac in this question). If the delta x is larger than the diameter of the region, we know that the electron is not confined to that region.
