1 Chapter 5 Nuclear Chemistry Guided Notes 5.1 Natural Radioactivity Learning Goal Describe alpha, beta, positron, and gamma radiation. Isotopes and Radiation Elements with atomic numbers ______ and higher usually have one or more isotopes with unstable nuclei. An unstable nucleus is ___________________, emitting small particles of energy called __________________ to become more stable. Radiation may take the form of o _________________________________ o _________________________________ o _________________________________ o _________________________________ Radioactive Isotopes An isotope of an element that emits radiation is called a _________________________________. When radiation is emitted, a radioisotope o may undergo a change in the number of _____________________ o may be converted to an atom of another element Atomic symbols for various isotopes are written with o the mass number in the upper left corner and the atomic number in the lower left corner of the element symbol o the mass number after the element _____________________ Example: __________________________________ Vocabulary to Know alpha particle becquerel (Bq) beta particle chain reaction curie (Ci) decay curve equivalent dose fission fusion gamma ray Chapter 5 Preview 5.1 Natural Radioactivity 5.2 Nuclear Equations 5.3 Radiation Measurement 5.4 Half-life of a Radioisotope 5.5 Medical Applications 5.6 Nuclear Fission and Fusion gray (Gy) half-life positron rad (radiation absorbed dose) radiation radioactive decay radioisotope rem (radiation equivalent in humans) sievert (Sv) 53 131 I
