Question

Which of the following statements is true of stable isotopes?Select one:a. They naturally decay into new elements.b. They have half-lives.c. They spontaneously release nuclear particles and energy.d. They cannot be detected with a radioactive detector.

Answer 1

Step-by-step explanation:

Stable isotopes are those that occur commonly in nature, in contrast to radioactive isotopes, which are unstable and thus transform over time into more stable elements, in a process known as radioactive decay.

So the following statements are for radioactive isotopes:

a.. They naturally decay into new elements.

b. They have half-lives.

c. They spontaneously release nuclear particles and energy.

Just the following statement is true for stable isotopes:

d. They cannot be detected with a radioactive detector.

Answer: d. They cannot be detected with a radioactive detector.
