Nuclear Decay EquationsLearning Goal:To predict the products of alpha emission, beta emission, positronemission, and electron capture.Radioactivity is the spontaneous emission of radiation from an unstablenucleus. There are five major types of radioactive decay:1. Alpha (a) radiation consists of helium nuclei. The heliumnucleus is a small particle containing two protons and twoneutrons (He).2. Beta (B) radiation consists of electrons. In nuclearequations, the standard format for representing a betaparticle using superscripts and subscripts ise.3. Positron emission results from the conversion of a proton inthe nucleus to a neutron. The ejected positron is a particlethat has the same mass as an electron but an oppositecharge. In nuclear equations, the standard format forrepresenting a positron using superscripts and subscripts isºe.14. Electron capture is the capture of an inner shell electron bya proton in the nucleus. The process emits gamma (7)radiation and results in a proton converting to a neutron.Gamma radiation consists of high-energy electromagneticradiation.5. Gamma (7) radiation consists of high-energy radiation, andcontains no particles and thus they have no mass. Innuclear equations, the standard format for representinggamma radiation using superscripts and subscripts is 7.Balancing a decay equationThere are two main rules to remember when balancing nuclear equations:1. The total of the superscripts in the reactants and products must be the same.2. The total of the subscripts in the reactants and products must be the sameFor an isotope of an element, the superscripts are mass numbers, and the subcripts are atomic numbers:Mass number →→→ AxAtomic number →→→ ZPart AWhere the mass number (A) is the sum of the number of proton and number of neutrons in the nucleus, atomic number (Z) is the number of protons in the nucleus, andchemical symbol (X) is the symbol of the specific element.Identify the nuclide produced when neptunium-237 decays by alpha emission:27Np He + ?Express your answer as an isotope using prescripts.▶ View Available Hint(s)SubmitΑΣΦA chemical reaction does not occur for this question.Part B?Chemical symbol== || ΑΣΦ90Identify the nuclide produced when thorium-234 decays by beta emission: 234 The + ?Express your answer as an isotope using prescripts.▸ View Available Hint(s)?<3 of 43Review | Constants | Periodic Table> Learning Goal:To predict the products of alpha emission, beta emission, positronemission, and electron capture.Radioactivity is the spontaneous emission of radiation from an unstablenucleus.
