Which bond is present in Cao?

An ionic bond is present in CaO (calcium oxide) because calcium is a metal and oxygen is a non-metal. Ionic bonds form between metal and non-metal atoms, where electrons are transferred from the metal to the non-metal, resulting in an electrostatic attraction between the two ions.


What is a O2?

O2- is an oxide ion which reacts with metal to form oxides of the metal. For example: MgO, Na2O


Is molecule O2 polar?

What type of bond does FeO form?

FeO forms an ionic bond. Iron (Fe) is a metal, and oxygen (O) is a non-metal, so they typically form ionic bonds where the metal atom loses electrons to the non-metal atom. In FeO, iron loses 2 electrons to oxygen to form the Fe2+ cation and the O2- anion.


Why calcium oxide is a compound rather than the metal or non metal?

Calcium oxide, CaO, is a compound.So it is neither a metal nor non-metal because those are ELEMENTS.Elements are 'made' of only one (or one kind of) atom(s).CaO is directly formed by the reaction ofthe metal : Ca (an uni-atomic element)withthe non-metal: O2 (a bi-atomic element)2 Ca + O2 --> 2 CaO

Is O2 covalent or ionic bond?

It is covalent. Ionic bonds only form between two different elements with a larger difference in electronegativity. O2 contains two atoms of the same element, so there is no difference in electronegativity.
