To know which isotope is most likely to have the greatest abundance in

nature, we look at the isotope whose atomic mass is closest to the average

 atomic mass.

The average atomic mass = 15.9994

The atomic masses of the isotopes are:

O-16: 15.995 amu

O-17: 16.999 amu

O-18: 17.999 amu


The one which is closest to the average mass is 
O-16: 15.995 amu, so it is

the one that is most likely to have the greatest abundance in nature.

Answer:

Explanation:

To know which isotope is most likely to have the greatest abundance in

nature, we look at the isotope whose atomic mass is closest to the average

atomic mass.

The average atomic mass = 15.9994

The atomic masses of the isotopes are:

O-16: 15.995 amu

O-17: 16.999 amu

O-18: 17.999 amu

The one which is closest to the average mass is O-16: 15.995 amu, so it is

the one that is most likely to have the greatest abundance in nature.
