Answer :
Final answer:
When sodium donates electrons to oxygen to form Na2O, it illustrates the transfer of electrons in the formation of an ionic compound.
Explanation:
In the formation of an ionic compound between sodium and oxygen, two sodium atoms donate one electron each to oxygen, creating Na+ and O2- ions. This leads to the formation of Na2O, where the number of electrons lost is equal to the number gained, following the law of conservation of matter.
