Radioactive Decay

Q. Part B - Rank the components of a radioactive beam according to their penetrating power α and β rays consist of particles, whereas γ rays are high-energy radiation and contain no particles and thus they have no mass. Given that the penetrating power decreases with mass, rank the rays according to their penetrating power. Rank the components from strongest penetrating power to weakest penetrating power. To rank items as equivalent, overlap them.

Radioactive Decay

Q. Part A - determining the charges on alpha (a), beta (β), and gamma (γ) rays. In the absence of an electric field, a radioactive beam strikes a fluorescent screen at a single point. When an electric field is applied, the radioactive beam is separated into three different components. One of the components is deflected toward the positive electrode because it is negatively charge, one of the components is deflected toward the negative electrode because it is positively charged, and one component is not deflected in any direction; instead, it moves along a straight path. Identify the charges possessed by the different components of the radioactive beam by observing their behavior under the influence of an electric field. Drag the appropriate items to their respective bins. γ rays, β rays, α rays
