Question

what is the relationship between natural abundance and stability?
choose all that apply
if the natural abundance is high, the isotope is stable
if the natural abundance is low, the isotope is stable
if the natural abundance is high, the isotope is unstable
if the natural abundance is low, the isotope is unstable

Explanation:

Stable isotopes are more abundant in nature because they do not decay over time. Unstable isotopes decay, so their natural abundance is low.

Answer:

If the natural abundance is high, the isotope is stable; If the natural abundance is low, the isotope is unstable.
