Under the usual chemical conditions oxygen gains 2 electrons to form ions.
However when ionized by electrical discharges or other high energy physical processes oxygen can lose any number of electrons to form ions (even all of its electrons).
Oxygen atoms have six valence electrons and tend to gain two more electrons to achieve a stable octet configuration. By forming two bonds, oxygen can share or gain electrons to complete its outer shell and become more stable. This tendency to form double bonds is due to oxygen's electronegativity and its preference to achieve a filled valence shell.
Two atoms of oxygen bind together through a covalent bond, where they share electrons to achieve a stable electron configuration. Each oxygen atom has six outer electrons in its valence shell and needs to gain two more electrons to have a full octet, so they share two electrons with each other, forming a double bond.
Oxygen needs to gain two electrons to achieve a stable electron configuration, which would give it a full outer shell of eight electrons (octet). This can be achieved through forming chemical bonds with other elements.
Nitrogen gains 3 electrons, oxygen gains 2 electrons, sulfur gains 2 electrons, and bromine gains 1 electron when forming ions.
Oxidation typically involves the loss of electrons or the gain of oxygen atoms. Oxidation does not necessarily involve the gain or loss of hydrogen atoms; however, in some cases, oxidation reactions can involve the loss of hydrogen atoms.
Some atoms lose electrons, some gain electrons, and some share electrons depending on what elements are involved and what compound is forming.
Atoms in the oxygen family can gain or share two electrons in order to achieve an octet of electrons.
Oxygen atoms have six valence electrons and tend to gain two more electrons to achieve a stable octet configuration. By forming two bonds, oxygen can share or gain electrons to complete its outer shell and become more stable. This tendency to form double bonds is due to oxygen's electronegativity and its preference to achieve a filled valence shell.
In forming compounds, atoms are engaged in either gaining or losing electrons. They may also share electrons, but that is also a form of gaining or losing electrons.
Oxygen molecules tend to prefer covalent bonding when forming compounds. This means that they will share electrons more readily. However, when forming an ionic compound, they will usually gain electrons rather than losing them.
Oxygen will gain two electrons to achieve a full outer shell.
An element in group 16/VIA, such as oxygen, is most likely to gain two electrons when forming an ionic bond. This is due to the fact that the atoms of the elements in group 16/VIA have six valence electrons and require two more to get a filled valence shell of 8 electrons (octet rule).
se and sometimes gain electrons. Atoms with eight valence electrons do not easily lose electrons

Oxygen is an oxidizer, it will gain electrons in a reaction to complete it's valence shell.
Oxygen will bond (share electrons) with other atoms to produce stable compounds ex. H2O ,O2
