Hello there,
Ione pairs of electrons that are present in a molecule of C2O are...
4
Each Oxygen forms two bonds with Carbon
Hope I Helped!

Magnets attract iron due to the influence of their magnetic field upon the iron. Before a piece of iron enters the magnet, the polarization of the irons atoms is random. When exposed to the magnetic field, the atoms begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well. This, in turn, creates an attraction between the two magnetized objects. This is why a piece of iron that is exposed to a magnet becomes magnetic for some time afterward.
An ionic bond is formed between metal and non metal when they exchange electrons.
The opposing bond would be covalent which is formed between non metal and non metal.
To form an ionic bond, pair any two metal and non metal that will exchange electrons such as LiBr, NaCl, etc.
Hope this helps!
It is called Hydrogen bonds
