Oxide ions are formed when oxygen gains two electrons to achieve a stable electron configuration. This usually occurs when oxygen reacts with metals or non-metals to form compounds such as oxides (e.g. MgO, CO2). The oxide ion has a 2- charge due to gaining two electrons.

What is the polyatomic ion oxide?

The polyatomic ion oxide is O2-, which consists of two oxygen atoms with a charge of -1. This ion is commonly found in compounds such as magnesium oxide (MgO) and carbon dioxide (CO2). Oxoanions containing oxygen and other elements can also form polyatomic ions with the oxide ion.


Does oxygen form ionic bonds?

Yes oxygen can form the oxide ion O2-, and the peroxide ion O22-


What ion is oxygen most likely to form?

Oxygen is most likely to form the oxide ion (O2-) by gaining two electrons.


What is the ionic bond between cuprous and oxide?

The ionic bond between cuprous (Cu+) and oxide (O2-) ions involves the transfer of electrons from the cuprous ion to the oxide ion to form an electrostatic attraction between the positively charged copper ion and the negatively charged oxygen ion. This results in the formation of cuprous oxide (Cu2O).


Which element reacts to form oxide ions?

Oxygen is the element that reacts to form oxide ions. Oxygen typically gains two electrons to become the oxide ion (O2-).


Is oxide acidic radical?

No, oxide is not an acidic radical. Oxide is a basic radical because it reacts with acids to form salts and water.


When copper combines with oxygen to form copper (II) oxide the charge of the copper ion is?

When copper combines with oxygen to form copper (II) oxide, the charge of the copper ion is +2. This is because in copper (II) oxide, each copper ion has lost two electrons to oxygen atoms, resulting in a +2 charge.

What is the positive and negative ion for calcium oxide?

The positive ion in calcium oxide is the calcium ion (Ca^2+), which has lost two electrons. The negative ion in calcium oxide is the oxide ion (O^2-), which has gained two electrons.


The formulas of the oxide and nitrate ions are respectively?

The formula for the oxide ion is O2-, and the formula for the nitrate ion is NO3-.


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.
