During alpha decay of a uranium atom, both alpha particles and gamma rays are emitted. the alpha particle is made up of 2 protons and 2 neutrons. an alpha particle is identical to the nucleus of helium, and is often written as superscript 4 subscript 2 baseline upper h e or superscript 4 subscript 2 baseline upper h e superscript plus 2 baseline. a uranium atom has an atomic number of 92 and an atomic mass of 238. it is written as superscript 238 subscript 92 baseline upper u. after the uranium atom undergoes radioactive decay, releasing a gamma ray, what are the atomic number and atomic mass of the daughter product? what are the atomic number and atomic mass of the alpha particle? based on the atomic numbers and masses of the resulting particles, an isotope of thorium and a helium atom remain after alpha decay of uranium-238. write the chemical equation that represents the alpha decay of uranium-238. polonium has an atomic mass of 212 and an atomic number of 84. write the chemical equation that represents the alpha decay of polonium-212. radium has an atomic mass of 226 and an atomic number of 88. write the chemical equation that represents the alpha decay of radium-226. next, consider beta (beta superscript minus baseline) decay. when a carbon atom undergoes beta decay, a neutron changes into a proton and an electron, which is a beta particle. the symbol for a beta particle is superscript 0 subscript minus 1 baseline e. the electron is emitted along with gamma rays. carbon has an atomic mass of 14 and an atomic number of 6. it is written as superscript 14 subscript 6 baseline upper c. after the carbon atom undergoes beta decay, what are the atomic number and atomic mass of the daughter product? what are the atomic number and mass number of the beta particle? based on the atomic numbers and masses of the resulting particles, an isotope of nitrogen and an electron remain after beta decay of carbon-14. write the chemical equation that represents the beta decay of carbon-14. iodine has an atomic mass of 131 and an atomic number of 53, written as superscript 131 subscript 53 baseline upper i. write the chemical equation that represents the beta decay of iodine-131. sodium has an atomic mass of 24 and an atomic number of 11, written as superscript 24 subscript 11 baseline upper n a . write the chemical equation that represents the beta decay of sodium-24
