Question
Consider the following schematic plots of orbital wavefunction $\left( \psi_{r} \right)$ against distance $(r)$ from the nucleus.
The figure representing two radial nodes in the orbital is
Options
A.C
B.D
C.A
D.B
Solution
Sol. [Key Concept: Radial nodes = n − l − 1]
(1s); number of radial node = 0
$(2s)$; number of radial node = 1
(3s); number of radial nodes = 2
$(3p)$; number of radial node = 1
