North Carolina Essential Standards and Clarifying Objectives:

Chm. 1.1 Analyze the structure of atoms and ions.

            1.1.4 Explain the process of radioactive decay using nuclear equations and half-life.

         Use the symbols for and distinguish between alpha (42He), and beta (0-1e) nuclear particles, and gamma (γ) radiation (include relative mass).

         Use shorthand notation of particles involved in nuclear equations to balance and solve for unknowns.

         Compare the penetrating ability of alpha, beta, and gamma radiation.

         Conceptually describe nuclear decay, including:

         Compare radioactive decay with fission and fusion.

        Decay as a random event, independent of other energy influences

        Using symbols to represent simple balanced decay equations

        Half-life (including simple calculations)
