Question

Choose the correct statements among the following.

• A. A node is a point in space where the wave-function $\psi$ has zero amplitude
• B. The number of maxima (peaks) in radial distribution in $n-l$
• C. Radial probability is $4\pi r^2{R}_{n,l}^2\left(r\right)$
• D. ${\psi }^2$ represents probability of finding electron

Answer 1

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

The correct options are
A ${\psi }^2$ represents probability of finding electron
B The number of maxima (peaks) in radial distribution in $n-l$
C A node is a point in space where the wave-function $\psi$ has zero amplitude
D Radial probability is $4\pi r^2{R}_{n,l}^2\left(r\right)$

A node is a point in space where the wave-function has zero value so $\psi$ has zero amplitude.
The number of maxima (peaks) in radial distribution in $n-l$.
${\psi }^2$ represents probability of finding electron and $4\pi r^2{R}_{n,l}^2\left(r\right)$ shows adial probability.
