Electron Capture: Nucleus Capturing Revolving Electron Shell

In summary, electron capture is a type of nuclear reaction where an electron from the innermost energy level is captured by the nucleus, resulting in the formation of a neutron and a decrease in the atomic number. This occurs when the nucleus is in an excited state and has a deficit of neutrons. The captured electron combines with a proton to form a neutron, creating a more stable element. Electron capture is significant in stabilizing atoms with a high proton-to-neutron ratio and is used in applications such as PET scans. It can only occur in larger, unstable atoms towards the end of the periodic table.

yes.

Electron capture is on of the processes for radioactive decay.
When a nucleus is deexcited, it releases photon-energy. During deexcitation the electron close to nucleus (i.e. usually s-shell) penetrated into the nucleus.
 

1. What is electron capture?

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.

2. How does electron capture occur?

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.

3. What happens to the electron after it is captured?

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.

4. What is the significance of electron capture?

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.

5. Can electron capture occur in all elements?

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.
