- AAn oxygen atom shares two electrons with two sodium atoms.
- BA sodium atom loses two electrons which are transferred to an oxygen atom.
- CA sodium atom shares its outer shell electron with two oxygen atoms.
- DTwo sodium atoms each lose one electron which are both transferred to one oxygen atom.
