I don't get it, how did it get oxygen - 18?

Thank you.

Maybe if you showed us the first part of the question it would provide more clues? i.e. what was part a) of the question about?

27 a) Give a reason why some nuclei are unstable.

ANS: proton to neutron ratio is too high or too low or the atom is too heavy (Z> 83)

What do you think?

The mass, itself, means nothing - it's the number of protons (too many).

Basically, they make the molecule using oxygen-18 rather than oxygen-16 so basically, it starts off with oxygen-18 rather than oxygen-16.
