Question

For radial probability distribution curves, which of the following is/are correct?

• A. The number of maxima in $2s$ orbital are two
• B. The number of spherical or radial nodes is equal to $n-l-1$
• C. The number of angular nodes are $l$
• D. $3d_{z^2}$ has two angular nodes

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A The number of maxima in $2s$ orbital are two
B The number of spherical or radial nodes is equal to $n-l-1$
C The number of angular nodes are $l$
D $3d_{z^2}$ has two angular nodes

The number of maxima in $2s$ orbital is two.(picture attached)
Also as we know,
Total no of nodes are $n-1$.
The number of spherical or radial nodes is equal to $n-l-1$.
The number of angular nodes are $l$.
