PSc.2.3.1 Compare nuclear reactions including alpha decay, beta decay, and gamma decay; nuclear fusion and nuclear fission.
• Compare the characteristics of alpha and beta particles and gamma rays – composition, mass, penetrability.
• Compare alpha, beta, & gamma decay processes –alpha decay reduces the mass of an atom by 4 & the atomic number by 2; beta decay increases the atomic number by 1(a neutron decays into a proton & electron) gamma rays are electromagnetic waves released from the nucleus with either alpha or beta particle.
• Compare the processes of fission (splitting of a very large atom) and fusion (joining of atoms) in terms of conditions required for occurrence, energy released, and the nature of products.
PSc.2.3.2 • Conceptually explain half-life using models.
• Perform simple half-life calculations based on an isotope’s half-life value, time of decay, and/or amount of substance.
