There are different kinds of Quantum Numbers: 1. Principal quantum number (n) describes the energy level of an electron in an atom. It can be expressed using the letters of an alphabet like K, L, M, N, O, P and Q energy level. answer
Answer (1)
Answer:The principal quantum number (n) describes the energy level of an electron in an atom. It's commonly represented by integers (1, 2, 3, ...) or alphabet letters:K (n=1), L (n=2), M (n=3), N (n=4), O (n=5), P (n=6), Q (n=7)These letters correspond to the electron shells or energy levels:K (n=1): 1s orbital (innermost shell)L (n=2): 2s, 2p orbitalsM (n=3): 3s, 3p, 3d orbitalsN (n=4): 4s, 4p, 4d, 4f orbitalsO (n=5): 5s, 5p, 5d, 5f, 5g orbitalsP (n=6): 6s, 6p, 6d, 6f, 6g orbitalsQ (n=7): 7s, 7p, 7d, 7f, 7g orbitalsThese quantum numbers help describe atomic structure and electron configuration.Other quantum numbers:1. Azimuthal quantum number (l): describes orbital shape2. Magnetic quantum number (m): describes orbital orientation3. Spin quantum number (s): describes electron spin
