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).

An oxide ion can be oxidized to an oxygen atom by an oxidizing agent that accepts electrons from the ion, causing it to lose electrons. This process results in the formation of an oxygen atom with a positive oxidation state.

Oxygen atom and oxide ion have same?
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.
How does an oxygen atom become an oxide ion?
An oxygen atom becomes an oxide ion by gaining two electrons. This allows it to achieve a stable electron configuration similar to the nearest noble gas, which is neon. The oxide ion has a charge of -2 due to its two extra electrons.
What formulas represent an oxide ion o o- o2- o2 o3?
The oxide ion is represented as O^2-. This means the oxygen atom has gained two electrons, giving it a charge of -2. The chemical formula for the oxide ion is O^2-.
What happens to the outer shell of a calcium atom when it reacts with an oxygen atom?
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.
Ion of oxygen?
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.
Oxygen atom and oxide ion have same?
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.
What is the electron configuration of the oxide ion (O2-?
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.
How many protons are in an oxide ion?
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.
What is the value of oxide ion and phosphate ion?
The oxide ion has a charge of -2, and the phosphate ion has a charge of -3.
What happens if oxide atom becomes an oxygen atom?
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.
How does an oxygen atom become an oxide ion?
An oxygen atom becomes an oxide ion by gaining two electrons. This allows it to achieve a stable electron configuration similar to the nearest noble gas, which is neon. The oxide ion has a charge of -2 due to its two extra electrons.
What is formed by an oxygen atom and called an oxide 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.
What formulas represent an oxide ion o o- o2- o2 o3?
The oxide ion is represented as O^2-. This means the oxygen atom has gained two electrons, giving it a charge of -2. The chemical formula for the oxide ion is O^2-.
Is -3 the charge in an oxide ion?
Yes, -3 is the charge in an oxide ion. This is because oxygen typically forms ions with a charge of -2, so in an oxide ion (O2-), the overall charge is -2 for each oxygen atom, giving a total charge of -1 for the molecule.
What does O with a little 2 the top mean in chemistry?
O2- is the symbol for the oxide ion, which is an oxygen atom that has gained two electrons. The oxide ion has a charge of -2.
What happens to the outer shell of a calcium atom when it reacts with an oxygen atom?
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.
Is double oxide a atom or molecule?
If you mean O2, then it is a molecule, though it would be more appropriate to call it "double oxygen" than "double oxide." Though it is usually just called oxygen. If you main O22-, then it is an ion, not a molecule or atom. It is called the peroxide ion.
