Oxygen Transformation: A Puzzling Phenomenon

[Pandus]

TL;DR

Free electrons does not affect oxygen. Or not?

Hi, guys.

Just found a missing thing in my brain: if atomic oxygen will meet free electron somewhere why doesn't it become fluorine or even argone?

Because the assignation of elements is based on the nucleus, not the electron shells. If an atom gives away or takes in additional electrons, it is called an ion.

But the charge of the nucleolus is 16. And the outer layer is missing two electrons. What would happen if electron will be attracted by P-layer?

No, the charge of the oxygen nucleus is 8. Its atomic mass is 16. Neither of which changes by adding an electron.
