Beta Decay of He3 Atom: Electron Emission vs. Shell Occupancy

In summary, the beta decay of the He3 atom results in the emission of an electron and antineutrino, leaving the atom with only one electron. The decay electron is emitted with more energy than the binding energy of the electron, allowing it to escape. This is due to the difference in energy between chemical and nuclear reactions.

Does this decay leave the He3 atom with only one electron? The only decay productsas far as I can tell are the electron and antineutrino, so it seems like the atom would only retain the original H3 electron.

Now if that's the case, why is the beta decay electron emitted rather than fitting into the lowest electron shell?

I don't have the specific numbers. However I believe the decay electron is emitted with a lot more energy and therefore escapes. The He3 nucleus picks up a swtray electron.

Correct. Energy released in the process is in the keV ranges. Binding energy for electron is going to be in the eV ranges.

So essentially it's the difference in energy between chemical and nuclear reactions?

In short, yes.
 

Related to Beta Decay of He3 Atom: Electron Emission vs. Shell Occupancy

What is Beta Decay?

Beta decay is a type of radioactive decay in which a nucleus emits a beta particle, which can be either an electron or a positron.

What is a He3 atom?

He3 (helium-3) is a rare isotope of helium that has one less neutron than the more common He4 isotope. It is often used in various scientific research, such as in nuclear physics and medical imaging.

What is electron emission in beta decay?

Electron emission, also known as beta minus decay, is a type of beta decay in which a neutron in the nucleus is converted into a proton, emitting an electron and an antineutrino in the process.

What is shell occupancy in beta decay?

In beta decay, the shell occupancy refers to the arrangement of electrons in the atomic orbitals of an atom. It plays a role in determining the stability of the nucleus and the likelihood of beta decay occurring.

What is the significance of comparing electron emission and shell occupancy in beta decay of He3 atom?

Studying the beta decay of He3 atom and comparing the electron emission and shell occupancy can provide insights into the nuclear structure and dynamics of atoms. It can also help in understanding the process of beta decay and its role in the stability of elements.
