Select our signature answer and leave behind the old instances with safety, affordability and effectivity. The following nuclei don’t lie within the band of stability. Answer c Since a γ ray has no mass the mass quantity and atomic quantity do not change. Lower frequency, lower-energy electromagnetic radiation is nonionizing, and better frequency, higher-energy electromagnetic radiation is ionizing. Α , β , β+ , and η could also be emitted from a radioactive element, all of that are particles; γ rays also could additionally be emitted.
