Question

why electron capture is more common in heavy atoms?​

Answer 1

Explanation:

Electron capture is a mode of beta decay in which an electron – commonly from an inner (low-energy) orbital – is 'captured' by the atomic nucleus. The electron reacts with one of the nuclear protons, forming a neutron and producing a neutrino. The daughter nucleus may be in an excited state.

Electron capture happens most often in the heavier neutron-deficient elements where the mass change is smallest and positron emission isn't always possible.

Electron capture happens most often in the heavier neutron-deficient elements where the mass change is smallest and positron emission isn't always possible.
