ordinary hydrogen. g. Alpha decay: process that unstable atoms can use to become more stable h. Beta decay: radioactive decay in which an electron is emitted. i. Gamma ray: penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei. j. Radioactive substance: atoms that decay naturally. They can give off alpha particles, beta particles and gamma radiation. 2. Using complete sentences, describe what happens to the nuclear force as the nucleus of an atom increases in size. Strong force, a fundamental interaction of nature that acts between subatomic particles of matter. The strong force binds quarks together in clusters to make more- familiar subatomic particles, such as protons and neutrons . It also holds together the atomic nucleus and underlies interactions between all particles containing quarks. 3. Which type of radiation contains the most energy? (Hint: It’s the one that is hardest to stop). Gamma-Rays
4. What type of material is able to stop each type of radiation: a. Alpha particle: sheet of paper b. Beta particle: aluminum plate c. Gamma ray: lead 5. Which two types of radiation are composed of particles? Gamma rays are electromagnetic radiation , like X- rays . The other two types of natural radioactivity are alpha and beta radiation , which are in the form of particles . Gamma rays are the most energetic form of electromagnetic radiation , with a very short wavelength of less than one-tenth of a nanometer. 6. Which type of radiation is composed of electromagnetic waves? The different types of electromagnetic radiation shown in the electromagnetic spectrum consists of radio waves , microwaves, infrared waves , visible light, ultraviolet radiation , X- rays , and gamma rays .
