20 Examples of Non-Metallic Oxides

The non-metallic oxides They are binary-type compounds, which are formed from the combination of a non-metal and oxygen, the latter in particular in its oxidation number -2. For example: Telluric anhydride, Carbon dioxide, Sulfuric anhydride.

It is common that they are also recognized under the name of acid oxides or anhydrides, and that they are formulated using the symbol of the non-metallic element together with the valence of oxygen (2) plus oxygen together with the valence of the non-metallic element. In mathematical simplification it is common for the formulation to lose that shape. On the other hand, the bond between oxygen and non-metal it is covalent.

While non-metallic oxides can appear in all three aggregation states, it is more common to find them in the gaseous form because their molecules they tend to be quite small and not very polar. In the same sense, it can be said that it is common for oxides of this type to have a rather low boiling and melting point.

About the physical properties

These non-metallic oxides can be said to have various colors and lack metallic luster. Solids tend to be more brittle, some are harder and others are softer. They are not good drivers of the hot and electricity. On the other hand, they tend to form oxoanion salts when they react with basic oxides.

Non-metallic oxides are often a root cause of environmental problems, since its presence in nature is a source of the diffusion of the greenhouse effect and acid rain.

Like almost everything related to the combinations of atoms to form chemical compounds, there are three ways to name them:
