Refer to the models provided and a periodic table to answer the following:
Model 1 Model 2
http://library.thinkquest.org/3471/radiation_types_body.html http://www.green-planet-solar-energy.com/nuclear-power-information.html
Model 3
http://www.hk-phy.org/energy/power/nuclear_phy02_e.html
In nuclear notation, the top left number is the mass and the
bottom number represents the charge.
For the beta particle to the right of Be-8 in Model 3, answer the following:
