Question

which statements best describe the process of radioactive decay? check all that apply. an unstable isotope changes until it reaches a different element that is unstable. an unstable isotope changes until it reaches a different element that is stable. a stable isotope changes until it reaches a different element that is unstable. a stable isotope changes until it reaches a different element that is stable. an unstable isotope changes until it reaches a different isotope of the same element that is unstable. an unstable isotope changes until it reaches a different isotope of the same element that is stable.

Explanation:

Radioactive decay is the process by which an unstable isotope undergoes changes (such as emitting particles or energy) to reach a more stable state. This can result in the formation of a different element that is stable or a different stable isotope of the same element. Stable isotopes do not undergo radioactive decay to become other elements or isotopes.

Answer:

An unstable isotope changes until it reaches a different element that is stable.
An unstable isotope changes until it reaches a different isotope of the same element that is stable.
