PPT-5.2 Nuclear Reactions

In the nuclear equation for alpha decay the mass number of the new nucleus decreases by 4 and its atomic number decreases by 2 Learning Goal Write a balanced nuclear equation showing mass numbers and atomic numbers for radioactive decay. Chapter 25. Marie Curie was a Polish scientist whose research led to many discoveries about radiation and radioactive elements. In 1934 she died from leukemia caused by her long-term exposure to radiation. You will learn about the various types of radiation and their effects.. Fission and Fusion. A brief history…. 1919: Ernest Rutherford experimented with bombarding nitrogen gas molecules with alpha particles emitted from bismuth-214. Discovery: faster moving particles were produced, and these could travel farther than the alpha particles!. Atoms consist of a nucleus surrounded by electrons. Chemistry is produced by interactions involving the electrons around the atom. t. his involves small energy changes (~0.01 eV) and can happen at room temperatures. ________________ involve changes in atomic nuclei. .
