The number of radial nodes for a 3p orbital is:

Correct answer: A. One

  • A. One
  • B. Two
  • C. Three
  • D. Infinite

Explanation

The number of radial nodes is given by the formula n - l - 1. For a 3p orbital, the principal quantum number n=3 and the azimuthal quantum number l=1. Therefore, the number of radial nodes is 3 - 1 - 1 = 1

About Atomic Structure

Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
