==Key Stage 5==
===Meaning===
'''Electron capture''' is a process in which a [[Proton-rich Nucleus|proton-rich nucleus]] absorbs an [[Inner Shell|inner-shell]] [[electron]], causing a [[proton]] to transmute into a [[neutron]] and [[emit]]ting a [[neutrino]].
===About Electron Capture===
*'''Electron capture''' typically occurs in [[Proton-rich Nucleus|proton-rich isotopes]].
*The '''captured electron''' combines with a [[proton]] to form a [[neutron]] and an [[Electron-neutrino|electron neutrino (ν<sub>e</sub>)]].
*'''Electron capture''' reduces the [[Atomic Number|atomic number]] by one while the [[Mass Number|mass number]] remains the same.
*'''Electron capture''' is often followed by the [[Emit|emission]] of [[X-ray]]s as [[electron]]s from higher [[Energy Level|energy levels]] fall into the lower [[Energy Vacancy|energy vacancy]].
*'''Electron capture''' helps to achieve a more stable [[Atomic Nucleus|nucleus]] by reducing [[proton]] number.
===Examples===
'''Electron capture''' occurs in [[Beryllium-7]] to form [[Lithium-7]].
