Lshell
Lshell, often written as L-shell, denotes the second electron shell of an atom, corresponding to the principal quantum number n = 2. In the classic spectroscopic notation used in early atomic theory, shells are labeled K, L, M for n = 1, 2, 3 respectively. The L-shell can hold up to eight electrons, distributed among the subshells 2s (capacity 2) and 2p (capacity 6).
In atomic structure, electrons fill shells in order of increasing energy. After the K-shell is filled, electrons
The energy of the L-shell lies above that of the K-shell, and the exact energies depend on
Overall, the Lshell is a foundational concept for understanding electronic structure, chemical behavior of light elements,
