false - if you can ionize the oxygen you can change its mass?
chemistry is not my thing, sorry

False - oxygen has not less than 17 different isotopes, of which three are stable -- namely, oxygen-16, 17, and 18, with oxygen-16 being the most common. Different isotopes of an element have different atomic masses.

No they do not. While oxygen always has 8 protons, the number of neutrons can vary, though 8 neutrons is most common. Stable, be relatively uncommon is oxygen with 9 neutrons, and 10 neutrons.

"There are three stable isotopes of oxygen that lead to oxygen (O) having a standard atomic mass of 15.9994(3) u. There are also 14 other isotopes that have unstable nuclei."

false. you can have an oxygen isotope, which means it has a different number of neutrons.
or you can ionize the atom, so you add or get rid of electrons, making it very slightly bigger or smaller.

nope, they can have different numbers of neutrons which affects mass
