when nucleus capture the electron revolving in the shell?
Electron capture is a type of nuclear reaction in which an electron from the innermost energy level (K-shell) is captured by the nucleus, resulting in the formation of a neutron and a decrease in the atomic number of the atom.
Electron capture occurs when the nucleus of an atom is in an excited state and has a deficit of neutrons. The nucleus then captures an electron from the innermost energy level to balance its composition and release energy.
After the electron is captured by the nucleus, it combines with a proton to form a neutron. This results in the formation of a new, more stable element with a lower atomic number.
Electron capture is an important process in nuclear physics as it helps to stabilize atoms with a high proton-to-neutron ratio. It is also used in some applications, such as in positron emission tomography (PET) scans.
No, electron capture can only occur in elements with a high proton-to-neutron ratio and in an excited state. This usually happens in larger, unstable atoms towards the end of the periodic table.
