### Equation

When using the heisenberg indeterminacy equation do we use the radius or diameter for delta x?

### Re: Equation

I believe if the question asks about an electron in the range of the nucleus, then you would use diameter as delta x. If the question asks about the electron being in the range of the radius of the nucleus, you would use the radius as delta x.

Whatever is given in the prompt is what should be used because it is about uncertainty, not the same exact measurement each time. It will depend on the situation
