What is electron capture?

Thanks so much for your question regarding electron capture. This is one of the means that a nuclear change can take place. When a nuclear change takes place, an atom changes its identity and is now an atom of a different element.Electron capture occurs when an inner-orbital electron (negatively charged) is captured by the nucleus (positively charged). The result is that a proton will combine with this electron and a neutron is formed. This process will reduce the atomic number by one and not changed the atoms mass. And example of this would be is Be-7 undergoes electron capture. Be-7 has four protons and 3 neutrons. Your atomic number will drop by one, thus a lithium atom is formed and the mass will remain the same. Li-7 is the result.reich-chemistry.wikispaces.comhttps://reich-chemistry.wikispaces.com/file/view/Electron_Capture.gif/31682535/Electron_Capture.gifAlso, note that gamma radiation is emitted along with electron capture to release excess energy.Hope this helps.
