Current Question (ID: 7559)

Question:
$\text{Correct statement among the following is:}$
Options:
  • 1. $\text{Number of angular nodes = n - l - 1}$
  • 2. $\text{Number of radial nodes = l}$
  • 3. $\text{Total number of nodes = n - 1}$
  • 4. $\text{All of the above}$
Solution:
$\text{Hint: Node is plane having zero electron density.}$\n\n$\text{Explanation:}$\n\n$\text{Angular node is also called a nodal plane. It is a plane that passes through the nucleus. Angular node is equal to the azimuthal quantum number (l).}$\n\n$\text{Radial node is a spherical surface where the probability of finding an electron is zero. The number of radial nodes increase with principle quantum number (n).}$\n\n$\text{Radial Nodes = n-l-1}$\n\n$\text{angular node = l}$\n\n$\text{Thus, option 3 is the correct answer.}$
