What does  mean? Tuesday, October 27 th, 2015

The Nuclear Equation A nuclear equation (chemical equation) is the symbolic representation of a reaction. Reactants (what you start with) are on the left of the arrow Products (what are being produced) are on the RIGHT of the arrow

Fission or Fusion? A + B  AB What is nuclear decay?

Barium-139 undergoes alpha decay. What does undergo mean?

Barium-139 undergoes alpha decay. What is alpha decay? (which particle is being produced?)

Barium-139 undergoes alpha decay.

To produce a gamma particle and a stable isotope… An alpha particle is shot at… Undergoes electron capture… Goes through positron emission…

Practice Problems 1. Americium-241 undergoes alpha decay. 2. Fluorine-18 undergoes positron emission. 3. A radioactive isotope undergoes beta decay to produce Techtinium Chromium-51 undergoes electron capture to produce a gamma particle and a stable isotope. 5. A radioactive isotope produces a gamma particle, an alpha particle and Pb-208.
