There are only two naturally occurring isotopes of helium on earth. If you increase the % abundance of helium-3, does the % abundance of helium-4 change? Why or why not?

(3 points) a. gases are compressible b. gases fill their containers completely c. the pressure of a gas is independent of the temperature d. gases have mass e. gases exert pressure f. the pressure of a gas is dependent on the volume g. gas pressure results from the collisions between gas particles h. gases have a definite volume and shape

Which of these conditions most likely produces an unstable isotope?

Can you me with this i really appreciate it
