over time, emitting radiation Explanation: Radioactive isotopes are unstable and undergo decay, releasing radiation in process. Question 3: How is the atomic mass of an isotope determined? A. By adding protons and ele
e number of protons but different numbers of neutrons, resulting in different mass numbers. Why do ions have a charge, and how is it determined? Ions have a charge because they have an unequal number of protons and electrons. The charge is positive
ight variations can occur due to mass differences. For example, in isotopic labeling, heavier isotopes can subtly influence reaction rates—a phenomenon known as the kinetic isotope effect. Physical Properties and Uses Isotopes can differ in physical prop
