Heya....❤❤❤

here is ur answer....

Stable isotopes. Naturally occurring oxygen is composed of three stable isotopes, 16O, 17O, and 18O, with 16O being the most abundant (99.762% natural abundance); thus oxygen (O) has a relative atomic mass of 15.9994(3). Known oxygen isotopes range in mass number from 12 to 24.

hope it helps...

Radioisotopes:

Fourteen radioisotopes have been characterized, with the most stable being 15O with a half-life of 122.24 s and 14O with a half-life of 70.606 s.

All of the remaining radioactive isotopes have half-lives that are less than 27 s and the majority of these have half-lives that are less than 83 milliseconds (ms). For example, 24O has a half-life of 61 ms. The most common decay mode for isotopes lighter than the stable isotopes is β+ decay (to nitrogen)and the most common mode after is β− decay (to fluorine).
