In electron capture, the electron combines with a proton to make a neutron. This changes the atomic number of the atom, so the process is a transmutation. Electron capture is a major decay mode for isotopes with too many protons in the nucleus. ... This is a transmutation, because it converts one element to another.
Is electron capture Exergonic or Endergonic?
Energy will be emitted during electron capture (i.e. it is an exergonic process), but will be absorbed in positron emission (i.e. it is an endergonic process).
Is electron capture radioactive decay?
Electron capture is the radioactive decay process by which an atom's inner orbital electron is absorbed within the nucleus followed by conversion of a proton to a neutron and emission of a neutrino (ve) 1.
