Question

question 8
isotopes are atoms of the select element, which means
they always have the sa select but a different
number of select a pair of isotopes would
be select

question 9
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:

Natural abundance refers to the amount of an isotope present in nature. Stable isotopes do not undergo radioactive decay. Unstable isotopes do. In nature, stable isotopes are more abundant because they do not decay away over time. Unstable isotopes decay, so their natural abundance is lower.

Answer:

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