Question

Radioactive isotopes of an atom are:

a.more scarce
b.more stable
c.less stable
d.more abundant

Answer 1

Radioactive isotopes of an atom aren't as stable as you would think, so the correct answer is: C. Less Stable

(I can verify this because I took the test.)

Hope this helps! Have a wonderfully wonderful day!

Cheers mate!

Answer 2

c.less stable

Step-by-step explanation:

A radioactive isotope is an isotope of an atom that has an unstable nucleus. This generally happens when the nucleus has a much larger number of neutrons compared to the number of protons: in this case, the nucleus tends to decay, emitting part of the neutrons (but also protons or electrons, depending on the type of decay), becoming a lighter nucleus which is more stable. Therefore, a radioactive isotope is generally not very stable.
