Question

Choose the correct statement among the following:

• A. ${\psi }^2$ represents the atomic orbital
• B. The number of nodes in radial distribution is $(n-1)$
• C. A node is a point in space around nucleus where the wave function $\psi$ has zero value
• D. All of the these

Answer 1

The correct option is D All of the these

${\psi }^2$ is the probability function. It gives the probability of finding the electron in the region of space around the nucleus.

For any ${}^{\prime }n{s}^{\prime }$ orbital, there are $(n-1)$ nodes.

A node is a region of space around the nucleus where the electron density is zero.
