3. Alpha Emission Alpha emission is when a radioactive nucleus emits a helium nucleus, and looses 2 protons and 2 neutrons.

4. Beta Emission During Beta Emission, a neutron is split into a proton and an electron, and then the electron is emitted out of the radioactive nucleus.

5. Positron Emission Positron emission is when the neutron to proton ratio is too small, so a proton turns into a neutron and a positron and the postiron is emitted. A positron is a particle with the same mass of an electron, but a positive charge.

6. Electron Capture Elctron capture is when the nucleus captures an electron which combines with a proton. The result of this combination is a neutron.

7. Gamma Emission Gamma emission happens when the nucleus is at an energy level that is too high. The nucleus emitts a gamma particle, bringing it down to a lower energy level.

Conclusion -Alpha emission is when a radioactive nucleus emits a helium nucleus, and looses 2 protons and 2 neutrons. -During Beta Emission, a neutron is split into a proton and an electron, and then the electron is emitted out of the radioactive nucleus. -Positron emission is when a proton turns into a neutron and a positron and the postiron is emitted. -Elctron capture is when the nucleus captures an electron which combines with a proton, creating a neutron. -Gamma emission is when the nucleus emitts a gamma particle, bringing it down to a lower energy level.
