• Each subshell is designated by a letter:

  • l = 0 indicates an s subshell.
  • l = 1 indicates a p subshell.
  • l = 2 indicates a d subshell.
  • l = 3 indicates an f subshell.

• Subshells are named by using the n value and the letter designation.

The subshell with n = 2 and l = 0 is called the 2s subshell.

The only orbital in the 2s subshell has n = 2, l = 0, and m l = 0.

The subshell with n = 3 and l = 1 is the 3p subshell.

It has three orbitals: n = 3, l = 1, and m l = +1, 0 and –1.

• Each of an atom’s orbitals is specified by a set of n, l, and m l values.

• These fix the orbital’s size, energy, shape, and spatial orientation.
