Atoms have Terms Symbols such as S (L=0), P (L=1), D (L=2), etc...In case of molecules, L no longer exists as other symbols are uesd: which ones?

Atomic and molecular symbols are shorthand notations used to represent elements and molecules in chemistry. They consist of one or two letters, often derived from the element's name, and may also include subscripts and superscripts to indicate the number of atoms or ions present.
The atomic and molecular symbols for elements are determined by their atomic number, which corresponds to the number of protons in the nucleus. For molecules, the symbols are determined by the composition and arrangement of atoms within the molecule.
The numbers in atomic and molecular symbols represent the number of atoms or ions of each element present in a molecule. The letters represent the element's chemical symbol, which is usually the first one or two letters of its name.
The periodic table is organized based on the atomic number and chemical properties of elements. The atomic and molecular symbols for elements are derived from their position on the periodic table. Additionally, the periodic table can be used to determine the number of protons, neutrons, and electrons in an atom based on its symbol.
There are a few exceptions and variations to atomic and molecular symbols, such as the use of different chemical symbols for the same element in different languages (e.g. Fe for iron in English and Fe for ferrum in Latin). Additionally, some elements have multiple symbols, such as carbon having both C and CO2 for carbon dioxide. There are also alternative notations used for isotopes and ions, such as 14C and C- for carbon-14 and carbonate ion, respectively.
