Quantum Numbers

Principal Quantum Number (n):
- Proposed by Bohr, denoted as 'n'.
- Represents the average distance between the electron and the nucleus, indicating the size of the atom.
Azimuthal Quantum Number (l):
- Known as the angular quantum number, proposed by Sommerfeld, denoted as 'l'.
- Determines the number of subshells or sublevels within an electron shell.
- Indicates the shape of subshells.
- Expresses the energy levels of subshells in increasing order: s < p < d < f.
- Defined by the relationship l = n - 1, where 'n' is the principal quantum number.
