Some people more loosely apply the term to refer to any compound where oxygen serves as the anion. Oxides that react with both are amphoteric. The -ide ending in Oxide suggests that this is an ion of a single element. Oxides typically react with acids or bases, sometimes both. Phosphorus pentoxide is a more complex molecular oxide with a deceptive name, the real formula being P4O10. In part, for this reason, alkali and alkaline earth metals are not found in nature in their metallic, i.e., native, form. An ionic compound is neutral, so the positive and negative charges are equal. Similarly, O 2− is the oxide ion, Se 2− is the selenide ion, and so forth. In the case of iron (II) oxide, one Fe2+ ion combined with one O2− ion creates a neutral compound. Since fluorine is more electronegative than oxygen, oxygen difluoride (OF2) does not represent an oxide of fluorine, but instead represents a fluoride of oxygen. The oxide ion has a charge of -2. Chemical symbol for bicarbonate? An oxide is a compound formed by the combination of oxygen and another element. Oxide ion. An oxide is a compound formed by the combination of oxygen and another element. For example, zinc is more reactive than copper, so it displaces copper (II) oxide to form zinc oxide: Apart from metals, hydrogen can also displace metal oxides to form hydrogen oxide, also known as water: Since metals that are reactive form oxides that are stable, some metal oxides must be electrolyzed to be reduced.
