The azimuthal quantum number is a quantum number for an atomic orbital that determines its orbital angular momentum and describes the shape of the orbital. The names of the electron shells come from a fellow named Charles G.
Barkla, a spectroscopist who studied the X-rays that are emitted by atoms when they are hit with high energy electrons. The general formula is that the nth shell can in principle hold up to 2 n2 electrons. Kumar Sarang answered this. Their is no full form of K L M N shells, it is only alphabatic representation of shells or orbital having subshell.
The names of the electron shell were given by a spectroscopist named Charles G Barkla. He named the innermost shell has k shell because he noticed that the X-rays emitted two types energies.
These energies were named as type A that is higher energy X-ray and type B that is lower energy X-ray. This outermost shell is known as the valance shell and electrons in this shell are called valance electrons. A completed outermost shell has valance of zero.

Subshells are labelled s, p, d, and f in an electron configuration.
Orbital Definition. In chemistry and quantum mechanics, an orbital is a mathematical function that describes the wave-like behavior of an electron, electron pair, or less commonly nucleons.
An orbital can contain two electrons with paired spins and is often associated with a specific region of an atom. The orbital names s, p, d, and f stand for names given to groups of lines originally noted in the spectra of the alkali metals.
These line groups are called sharp, principal, diffuse, and fundamental. The letters and words refer to the visual impression left by the fine structure of the spectral lines which occurs due to the first relativistic corrections, especially the spin-orbital interaction. S - block elements are the elements with valence electrons in the s orbital. Elements in column 1 have one valence electron. Elements in column 2 have two valence electrons. S - block elements are very reactive.
So known elements do not possess 8s or 9s electronic configuration but in laboratories, elements with higher atomic orbitals can be generated which are definitely not stable. Orbitals have no physical existence and can be thought as smeared out. They have an even more complex angular distribution than the p orbitals.
For most of them it is a "clover leaf" distribution something like 2 dumbbells in a plane. Hund's Rule. Hund's rule : every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin. In other words, the KLMN OP notation only indicates the number of electrons an atom has with each principal quantum number n.
The SPDF notation subdivides each shell into its subshells.
