Radioactive Decay: is the process by which a nucleus of an unstable atom loses energy by emitting particles of ionizing radiation. A material that spontaneously emits this kind of radiation—which includes the emission of energetic alpha particles, beta particles, and gamma rays—is considered RADIOACTIVE.
A brief periodic table trends activity for high school and genchem college students to learn about the 5 trends of the periodic table: ionization energy, electron affinity, metallic character, atomic radius, and electronegativity.
Descriptions and diagrams of the 5 trends of the periodic table including ionization energy, atomic radius, electron affinity,electronegativity, and metallic character. Descriptive images and a periodic table trends activity for students.
