felectrons
Felectrons is a term that lacks a single, universally accepted definition in mainstream science. In many discussions it appears as an informal or context-dependent label, and in formal literature it is often a misspelling or shorthand for f-electrons—the electrons occupying f orbitals in certain elements.
In chemistry and solid-state physics, f-electrons refer to the electrons in the 4f and 5f subshells found
Outside of established science, felectrons may be used in speculative or fictional contexts to denote hypothetical
Because the term is ambiguous, readers should rely on the surrounding context to determine the intended meaning.
