The radioactive isotope 247BK decays by a series of a-particle and B-particle productions, taking 247BK through many transformations to end up as 207Pb. In the complete decay series, how many a particles and how many B- particles are produced? A) 10 a particles and 10 B- particles. B) 10 a particles and 5 B- particles. C) The number of a particles cannot be determined. D) The number of B- particles cannot be determined. E) Neither the number of a particles nor ß- particles can be determined.

Question 5 In the reaction shown, the radiation produced is a(an) 66 Cu → Zn + O a. neutron O b. alpha particle O c. positron O d. beta particle O e. gamma ray

Radon (222 g/mol) is a naturally occurring radioactive gas found in the ground and in building materials. It is easily inhaled and emits alpha particles when it decays. Cumulative radon exposure is a significant risk factor for lung cancer.

Write the particle that is emitted in the following nuclear processes: Gold-198 decays to mercury 198 Radon-222 decays to polonium-218 Potassium-40 decays to argon-40

Identification and Characterization of Unstable and Stable Nuclei Nuclear stability can in general be predicted based on the following considerations: • Nuclei with 84 protons or more are unstable. • Nuclei containing a magic number of protons and/or neutrons tend to be stable. • Stable nuclei often contain even numbers of protons and/or neutrons. These factors are reflected in the given graph (Figure 1). which shows the valley of stability as a function of number of neutrons and protons.
