### 1B. Quantum Theory and model of an atom

1B. 25) 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

How do we draw the model to show the atom in a one-dimensional box?

You would draw the atom as a circle and label its radius and diameter, since the diameter of the atom is the uncertainty in position for the electron in this problem.

You could also draw in possible paths the electron could take/be to show that you are uncertain of where exactly the electron is.
