For a 4d orbital:
The angular nodes for \( l = 2 \) is \( l = 2 \). The radial nodes are given by \( n - l - 1 \), so for \( n = 4 \) and \( l = 2 \), the radial nodes are \( 4 - 2 - 1 = 1 \). Thus, the total number of nodes is \( 2 + 1 = 3 \).
The figures below show:
Which of the following points in Figure 2 most accurately represents the nodal surface shown in Figure 1?
The wavelength of spectral line obtained in the spectrum of Li$^{2+}$ ion, when the transition takes place between two levels whose sum is 4 and difference is 2, is
