Electron capture

Electron capture (K-electron capture, also K-capture, or L-electron capture, L-capture) is a process in which the proton-rich nucleus of an electrically neutral atom absorbs an inner atomic electron, usually from the K or L electron shell.

Isotopes of fluorine

Although fluorine (9F) has 18 known isotopes from 14F to 31F and two isomers (18mF and 26mF), only one of these isotopes is stable, that is, fluorine-19; as such, it is a monoisotopic element.
