Reacting with another elements oxygen forms oxides.
An oxygen atom can only be oxidized by some element with an equal or higher electronegativity. So, oxygen can be oxidized by fluorine (e.g., OF2) or by another oxygen atom (e.g., O2).
The oxygen atom and oxide ion have the same number of protons, which is 8. The oxide ion, however, has gained two electrons, giving it a charge of -2, whereas the oxygen atom is neutral.

When a calcium atom reacts with an oxygen atom, the calcium atom loses two electrons from its outer shell and the oxygen atom gains those electrons. This forms a calcium ion with a 2+ charge and an oxygen ion with a 2- charge. These ions then bond together to form calcium oxide.
An ion of oxygen with a positive charge is called a "positively charged oxygen ion" or "oxygen cation." This type of ion is less common than the negatively charged oxygen ion (oxygen anion). It forms when an oxygen atom loses one or more electrons.
An oxygen atom can only be oxidized by some element with an equal or higher electronegativity. So, oxygen can be oxidized by fluorine (e.g., OF2) or by another oxygen atom (e.g., O2).
If an oxide atom loses one or more oxygen atoms, it would no longer be considered an oxide. Instead, it would become a different compound based on the remaining elements present. Oxides generally consist of oxygen combined with another element, so removing oxygen would change the compound's identity.
An oxide ion has 8 protons. This is because it is an oxygen atom that has gained 2 electrons to become negatively charged. The number of protons remains the same as the number of protons in a neutral oxygen atom.
The oxygen atom and oxide ion have the same number of protons, which is 8. The oxide ion, however, has gained two electrons, giving it a charge of -2, whereas the oxygen atom is neutral.
The electron configuration of oxygen in the oxide ion (O2-) is 1s2 2s2 2p6 (equivalent to the configuration of a neon atom), as the oxide ion has gained two extra electrons compared to a neutral oxygen atom.
The Lewis structure for a nitric oxide ion (NO) has a nitrogen atom in the center with a single bond to an oxygen atom and a positive charge on the nitrogen atom.
The oxygen atom would have a charge of -2 after gaining two electrons to become an oxygen ion.

An oxygen atom that gains two electrons forms an oxide ion, which has a charge of -2. This occurs when oxygen typically reacts with metals or non-metals to form ionic compounds called oxides.
O=oxygen atom, o2=oxygen molecule, o2-=oxide, o22-=peroxide, o2-=superoxide, o3=ozone.
Oxygen becomes a negatively charged ion, specifically the oxide ion, when it combines with a metal. The oxide ion has a charge of -2.
Oxygen gains 2 electrons to become an oxide ion (O2-).
