A helium ion that comes within about 10 fm of the center of the nucleus of an atom in the sample may induce a nuclear reaction instead of simply scattering. Imagine a helium ion with a kinetic energy of 3.0 MeV heading straight toward an atom at rest in the sample. Assume that the atom stays fixed. What minimum charge can the nucleus of the atom have such that the helium ion gets no closer than 10 fm from the center of the atomic nucleus? (, and is the magnitude of the charge of an electron or a proton.) (a) 41,000 V/m; (b) 250,000 V/m; (c ) 500,000V/m; (d) 6,000,000 V/m

PROBLEM SOLVING 2 Mr. Albedo stumbled upon an unknown material in an abandoned laboratory. He believes that this material is radioactive. He brought it to his laboratory at Dragonspine for identification. Then, he obtained a sample weighing 10.5 g. After 6 hours, the weight of the sample decreased to 0.171 g. 1. Using the data gathered by Mr. Albedo, calculate the half-life (in hours) of the radioactive sample. Express answer in 3 SF. 2. From the given list below, determine the possible identity of the unknown sample. Isotope Half-life Ra-224 3.66 days Pb-212 10.6 hours Bi-212 60.6 minutes TI-208 3.05minutes 3. Mr. Albedo found out that the sample was emitting alpha particles. Write the nuclear reaction involved in this process.

Nuclear Decay Equations Learning Goal: To predict the products of alpha emission, beta emission, positron emission, and electron capture. Radioactivity is the spontaneous emission of radiation from an unstable nucleus. There are five major types of radioactive decay: 1. Alpha (a) radiation consists of helium nuclei. The helium nucleus is a small particle containing two protons and two neutrons (He). 2. Beta (B) radiation consists of electrons. In nuclear equations, the standard format for representing a beta particle using superscripts and subscripts ise. 3. Positron emission results from the conversion of a proton in the nucleus to a neutron. The ejected positron is a particle that has the same mass as an electron but an opposite charge. In nuclear equations, the standard format for representing a positron using superscripts and subscripts is ºe. 1 4. Electron capture is the capture of an inner shell electron by a proton in the nucleus. The process emits gamma (7) radiation and…
