The plot to the right is like the ones shown in class measuring the distance of a bound electron from the nucleus. Answer the following about the orbital it describes.

a$)$ How many radial nodes does this orbital have?

b$)$ If the orbital has one angular node, what are the values of $n$ and $l?$

c$)$ Draw a picture of the angular shape of the orbital.

d$)$ What quantum number would you need to assign to put the correct axes on your orbital picture from part $c?$ Can you tell this information from the radial plot?

e$)$ List two radii where the phase of the electron wavefunction will not have the same sign.
