Neither. An oxide is a compound consisting of a combination of atoms, a metal and oxygen.
2 atom potassium and 1 atom oxygen
First of all you can have either carbon monoxide or carbon dioxide, and maybe a couple of others, but not just carbon oxide. Secondly an atom is of only 1 element and this compound contains 2 types of element (carbon and oxygen), which makes it a molecule.
Oxidation is the combination of a substance with oxygen. It is a reaction in which the atoms of an element lose electrons and the charge of the element increases.
There is no ELEMENT with the symbol "DO" however, it would be the molecule which is one atom of deuterium (D) and one atom of oxygen (O). Deuterium is an isotope of hydrogen. This molecule would be called deuterium oxide.
An oxide always has at least one oxygen atom as well as at least one atom of a different element.
An oxide /ˈɒksaɪd/ is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2- atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2.
If an oxide atom loses one or more oxygen atoms, it would no longer be considered an oxide. Instead, it would become a different compound based on the remaining elements present. Oxides generally consist of oxygen combined with another element, so removing oxygen would change the compound's identity.
An oxygen atom can only be oxidized by some element with an equal or higher electronegativity. So, oxygen can be oxidized by fluorine (e.g., OF2) or by another oxygen atom (e.g., O2).
Sand is primarily composed of silicon dioxide (SiO2), which is the oxide of the element silicon.
No, aluminum oxide is not an element. Indeed, nothing called an "oxide" can be an element, as this term indicates that the substance is combined with oxygen and is therefore a compound, not an element.
No. It is not. Iron is an element. Oxygen is an element. Iron Oxide is a compound.
Elements only have one kind of atom throughout. Iron dioxide has both iron and oxygen so it isn't an element.
