The total number of nodes are given by

Options

  1. A(n+1)
  2. B(n-l-1)
  3. C(n-1)
  4. D(n-l+1)

Correct answer

C. (n-1)

Step-by-step solution

In quantum mechanics, the total number of nodes in an atomic orbital is defined as the sum of radial nodes and angular nodes. The number of radial nodes is given by (n - l - 1) . The number of angular nodes is given by l . Therefore, the total number of nodes is (n - l - 1) + l = n - 1 . Answer: (n-1)
