MDCAT Chemistry MCQ #775

  1. Question 1

    Q1. Calculate the number of nodes in the 3d orbital.

    • A) 0
    • B) 1
    • C) 2
    • D) 3

    Answer: 1

    Explanation: Number of nodes = n-l-1, for 3d, n=3, l=2, nodes = 0. Radial nodes = n-l-1 = 0, total nodes = 0 + angular nodes = 2, but radial nodes = 0. Option C is incorrect.
