It has gained 2 electrons.
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.
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.
The percentage of oxygen in sodium oxide is 72.7% as the chemical formula for sodium oxide is Na2O, which contains 2 oxygen atoms and 1 sodium atom. To calculate the percentage of oxygen, you divide the molar mass of oxygen by the molar mass of sodium oxide and multiply by 100.
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 ionic formula for calcium and oxygen is CaO. Calcium has a +2 charge while oxygen has a -2 charge. To balance the charges, one calcium atom combines with one oxygen atom to form calcium oxide.
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.
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.
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.
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.
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.

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.
No. On its own oxygen is neutral. Its ion, the oxide ion, has a negative charge
The ionic formula for calcium and oxygen is CaO. Calcium has a +2 charge while oxygen has a -2 charge. To balance the charges, one calcium atom combines with one oxygen atom to form calcium oxide.
Aluminum oxide is a neutral compound, so it does not have a net charge. Each aluminum atom in aluminum oxide has a charge of +3, while each oxygen atom has a charge of -2, resulting in a balanced compound with no overall charge.
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.
Oxygen can have a negative charge when it gains an extra electron, forming an oxide ion (O2-). This extra electron gives the oxygen atom a negative charge, making it more stable by achieving a full outer electron shell.
