What is the minimum uncertainty in the speed of an electron confined to within a lead atom of diameter 350. pm?
Is the uncertainty in position 350. pm in this problem?

The uncertainty in position would be 350. pm, but in order to apply it to the equation you need to convert this to meters so the units will align with one another.

I believe the diameter of the atom is twice of "delta x," it looks like the question wants you to put 1/2 of that diameter into the uncertainty equation in delta x and solve of velocity.

So, to confirm that I am solving this problem correctly, whenever the diameter is given, that represents the uncertainty in position-delta x? Also why would the problem want you to use only 1/2 of the diameter given?
