Quantum number values for 2p orbitals are:

Correct answer: A. n=2,l = 1

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

Explanation

There are two types of quantum numbers: azimuthal quantum number(l) and principal quantum number(n). The principal quantum number,n, is actually the number of shells. Azimuthal quantum number, l, is actually the number of subshells. According to n-1 rule for the azimuthal quantum number, l will be equal to 1. "2p", where 2 represents the "n=2" and p represents the second subshell hence "l=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.
