Which of the following point in Figure 2 most accurately represents the nodal surface as shown in Figure 1?
Options
- ABoth Statement I and Statement II are true
- BBoth Statement I and Statement II are false
- CStatement I is true but Statement II is false
- DStatement I is false but Statement II is true
Correct answer
D. Statement I is false but Statement II is true
Step-by-step solution
The 2s orbital has one radial nodal surface, which is a spherical surface shown in Figure 1. A nodal surface is where the electron probability density (and wave function) equals zero, meaning _ 2s (x) = 0 . From the wave function graph in Figure 2, point B represents where the wave function crosses zero on the x-axis, indicating the location of the radial node. Points A and C show maximum and minimum values respectively, while point D shows a non-zero region beyond the node.
