What is the most abundant isotope of oxygen?
Oxygen-16 is by far the most abundant (99.7%).
Nitrogen 14 is by far the most abundant isotope (99.63% abundant). An easy way to figure out which one is the most abundant is to look at the periodic table. The mass on the periodic table is the weighted average of all possible isotopes. The atomic mass of nitrogen is 14.00674. You can gather from this that the most abundant isotope is N-14, since the number is VERY close to 14. It is also possible…
The number of protons would be 8 and 8 corresponding electrons, the number of neutrons will very with the isotope of that element .To say thet the most abundant isotope is oxygen-16 (99.76%) a small portion is oxygen-17(0.038%) and a negligible amount of oxygen-18(0.21%) because 0-18 is fount mainly in ice in the antarctic. All of the naturally occurring isotopes are stable.
