* Oxide: A compound containing one oxygen atom per molecule or formula unit. Examples include:
* Sodium oxide (Na₂O): Contains two sodium atoms and one oxygen atom.
* Iron(III) oxide (Fe₂O₃): Contains two iron atoms and three oxygen atoms (but each iron atom has one oxygen atom attached to it, hence the name "oxide").
* Dioxide: A compound containing two oxygen atoms per molecule or formula unit. Examples include:
* Carbon dioxide (CO₂): Contains one carbon atom and two oxygen atoms.
* Silicon dioxide (SiO₂): Contains one silicon atom and two oxygen atoms.
In summary:
* Oxide: Contains one oxygen atom per molecule/formula unit.
* Dioxide: Contains two oxygen atoms per molecule/formula unit.
It's important to note that there are also trioxide (three oxygen atoms), tetraoxide (four oxygen atoms), and so on, depending on the number of oxygen atoms present in the compound.
