Current Question (ID: 7556)

Question:

$\text{The incorrect statement about the nodal plane among the following is:}$

Options:

1. $\text{A plane on which there is a zero probability of finding an electron.}$
2. $\text{A plane on which there is maximum probability that the electron will be found.}$
3. $\psi^2 \text{ is zero at nodal plane.}$
4. $\text{None of the above.}$

Solution:

$\text{Hint: In nodal plane, electron is not present.}$\n\n$\text{Explanation:}$\n\n$\text{In the quantum mechanical model of the atom, a nodal plane is a region around the nucleus where the probability of finding an electron is zero or almost zero.}$\n\n$\text{The number of nodal planes in an orbital is equal to the azimuthal quantum number.}$
