* Opposite charges attract: Sodium ions have a positive charge, while oxygen ions have a negative charge. This fundamental principle of electromagnetism dictates that opposite charges attract each other.
* Ionic bonding: When sodium and oxygen react, sodium loses an electron to become a positively charged ion (Na+), and oxygen gains two electrons to become a negatively charged ion (O2-). This transfer of electrons creates an ionic bond, which is the electrostatic attraction between oppositely charged ions.
* Strong attraction: The attraction between sodium and oxygen ions is relatively strong due to the significant charge difference between them. This strong attraction is what holds together ionic compounds like sodium oxide (Na2O).
In simpler terms: Imagine two magnets, one with a north pole and one with a south pole. They will naturally snap together because opposite poles attract. Similarly, the positive sodium ions are attracted to the negative oxygen ions.
