An oxygen atom gains 2 electrons when it becomes an ion because it wants a full valence shell (as in, its outer energy level is trying to reach 8 electrons).
Losing or gaining electrons is known as ionization, a process that occurs when an atom gains or loses electrons to achieve a stable electron configuration. Atoms tend to lose or gain electrons to achieve a full outer shell, following the octet rule. This process forms ions, which are electrically charged particles.
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.
metallic bond
Common valences are 5 or 3.
It is a neutral atom of the element gaining or losing one or more electrons.

Atoms tend to lose or gain electrons to achieve a full outer shell, following the octet rule. This process forms ions, which are electrically charged particles.
The process of losing or gaining electrons is called oxidation or reduction, respectively. Oxidation involves the loss of electrons, while reduction involves the gain of electrons. These two processes occur simultaneously in a redox reaction.
Chemical bonds can be only produced by gaining, losing or sharing electrons. If a compound is formed by losing or gaining electrons, it is called an ionic bond and if by sharing electrons, it is called a covalent bond.
After losing or gaining electrons, atoms will form ions. If an atom loses electrons, it becomes a positively charged ion, while if it gains electrons, it becomes a negatively charged ion. This process results in the formation of stable electronic configurations.

An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
by gaining or losing electrons.
If you meant the opposite of oxidation, that would be "reduction". Oxidation is the act of losing an electron, while reduction is the act of gaining an electron.
