Quantum number values for 2p are

Correct answer: A. n=2 l=1

  • A. n=2 l=1
  • B. n=1 l=2
  • C. n=2 l=0
  • D. n=1 l=1

Explanation

For the 2p orbital, the principal quantum number (n) is 2, indicating that the electron is in the second energy level or shell. The azimuthal quantum number (l) is 1, which corresponds to the p orbital shape. So this answer is correct. It is incorrect because the principal quantum number (n) cannot be smaller than the azimuthal quantum number (l). The value of n must be equal to or greater than l. It is incorrect because for the p orbital, the azimuthal quantum number (l) must have a value of 1, 0, or -1. It cannot be 0.It is incorrect because for the 2p orbital, the principal quantum number (n) must be 2, not 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.
