### 1.B.25

Question 1.B.25 asks " What is the minimum uncertainty in the speed of an electron confined within a lead atom of diameter 350. pm? Model the atom as a one-dimensional box with a length equal to the diameter of the actual atom."

What does it mean by model the atom as a one-dimensional box?

It essentially just means that you use the diameter of the atom to use as the uncertainty in position of the electron. The model of the one dimensional box is a line where the position of the electron in uncertain, it just means you don't have to find the area of the atom.
