Step 1

(1) The principal quantum number can be given by the below mentioned formula:

Principal quantum number(*n*) = Number of nodes+1

As per the given curve, there are 4 nodes

Substitute the same in the above formula,

Principal quantum number(*n*) = 4 + 1 = 5

2) There are 4 nodes located.

Step 2

3) The radial wave function curve is represented by red in the image given. The values for the location of nodes on the X−axis is to be selected by choosing the points, where the curve cuts the X−axis. The curve cuts the X-axis at 4 different points which are 1.9, 6.4,13.9 and 27 (most appropriate from the given list)
