Chapter 13 Nuclear Chemistry

Alpha Emission

_______________: An alpha particle is a helium nucleus with two protons and two neutrons.

Gamma Emission

_________________: Gamma emission is the giving off of high-energy, short-wavelength photons similar to X-rays.

Positron Emission

_____________: A positron is essentially an electron that has a positive charge instead of a negative one.

Electron Capture

______________: The four decay modes described above all involve the emission or giving off a particle; electron capture is the capturing of an electron from the energy level closest to the nucleus(1s) by a proton in the nucleus
