the transformation of the original atom the parent nuclide into a different atom the daughter nuclide The key players in this process include alpha particles Helium nuclei beta particles electrons or positrons and gamma rays highenergy photons Each type of emission affects the atomic number and mass number of the nucleus differently Types of Radioactive Decay Alpha Decay The emission of an alpha particle decreasing the atomic number by 2 and the mass number by 4 Beta Decay The emission of a beta particle increasing the atomic number by 1 and leaving the mass number essentially unchanged Gamma Decay The emission of gamma rays which dont alter the atomic number or mass number they simply reduce the energy of the nucleus The Role of HalfLife A crucial concept related to radioactive decay is the halflife The halflife is the time it takes for half of the atoms in a given sample to decay Its a constant for a given radioactive isotope and doesnt depend on external factors like temperature or pressure This characteristic makes radioactive decay predictable and valuable in diverse applications The Student Exploration Nuclear Decay Gizmo A Deeper Look 2 The Gizmo allows students to visualize
