How to judge a chemical formula is not an oxide
Two elements, one of which is oxygen, that is, oxide.However, generally referred to as the oxide of oxygen is relatively non-metallic relatively strong binary oxygen compounds.
Note that the most critical point is that all the oxygen elements must be -2 price, because there are some exceptions such as sodium peroxide, potassium oxide, but also by the two elements, one of which is the oxygen element, but the peroxide Sodium oxygen element is -1 price, the oxygen element of potassium oxide is -0.5. On the contrary which chemical formula is not an oxide at a glance
While KMnO4 KClO3 contains oxygen but not an oxide.
Oxide Definition: consists of two elements, one of which is a compound of oxygen, such as CO2 Fe2O3, H2O
