When sodium metal burns in oxygen to form sodium oxide, there is a transfer of electrons between the sodium and oxygen atoms, resulting in changes to their oxidation states, signifying a redox reaction.
During the reaction where sodium metal burns in oxygen to form sodium oxide, significant changes occur to the atoms involved. Sodium atoms lose electrons and transition from a neutral state to a +1 oxidation state. On the other hand, oxygen atoms gain electrons and shift from a neutral state to a -2 oxidation state. This transfer of electrons indicates a redox reaction, where electrons are exchanged between the sodium and oxygen atoms.
