What is the angular quantum number?

1 Answer

Angular Quantum number describes the subshell/sub energy level....

Quantum numbers can be used to describe the exact location of an electron.

There are four quantum numbers:

  1. n - describes the energy level

  2. ℓ - describes the subenergy level (0 to n-1 )

  3. mℓ - describes the orbital ( -ℓ to +ℓ )
  4. ms - describes the spin (clockwise or anti clockwise : or )
