Current Question (ID: 7560)

Question:
$\text{Orbitals having two spherical nodes are:}$
Options:
  • 1. $\text{2s}$
  • 2. $\text{4s}$
  • 3. $\text{3d}$
  • 4. $\text{6f}$
Solution:
$\text{Hint: Use the formula to calculate spherical nodes.}$\n\n$\text{Explanation:}$\n\n$\text{A spherical node is known as a radial node. Radial nodes are given by (n-l-1), where n-1 is the total number of nodes, and (l) is the number of angular nodes. (n is the principal quantum number, and (l) is the angular momentum quantum number.}$\n\n$\text{Use the formula given below to calculate spherical nodes}$\n\n$\text{No. of spherical nodes = n-l-1;}$\n\n$\text{The 6f contains two spherical nodes. Calculation is as follows = 6-3-1 = 2}$\n\n$\text{So, option 4 is the correct answer.}$
