- Certain heavy, unstable nuclei will eject a helium nucleus (also known as an alpha particle) in a process known as alpha decay. The following nuclei undergo alpha decay. Write these reactions out in symbolic form.
- 23892U
- 20984Po
- 22688Ra
- the daughter nucleus from part c.
- the daughter nucleus from part d.
- In certain unstable nuclei, a neutron will transmute into a proton, an electron, and an electron antineutrino. The proton remains in the nucleus and the electron (also known as a beta particle) and electron antineutrino (often just called a neutrino) are both ejected from the nucleus. The following nuclei undergo beta decay. Write these reactions out in symbolic form.
- 146C
- 20982Pb
- 31H
- Some nuclei become excited (or metastable) during nuclear reactions. When they return to their ground state they emit a highly energetic photon (a gamma ray photon). The following metastable nuclei undergo gamma decay. Write these reactions out in symbolic form.
- 27m13Al
- 87m30Sr
- 99m43Tc
