Non-metal oxides

from Wikipedia, the free encyclopedia

As a non-metal oxides are called chemical compounds from a nonmetal and oxygen .


Many non-metals react very easily and violently with oxygen (e.g. sulfur or phosphorus ), others only under certain conditions ( e.g. chlorine ) and some not at all ( e.g. helium ).


Most non-metal oxides form acids with water . For example, sulfur dioxide and water are used to produce sulphurous acid . That is why they are also called acid oxides or acid anhydrides. They neutralize bases. All non-metal oxides contain oxygen in a predominantly covalent bond. The coordination number of oxygen in covalent oxides varies between 1 and 3.

List of non-metal oxides

The following list shows the most common oxides in addition to the respective non-metallic chemical elements .

Non-metal Non-metal oxides
hydrogen Water , hydrogen peroxide
sulfur Sulfur dioxide , sulfur trioxide
phosphorus Phosphorus pentoxide
carbon Carbon monoxide , carbon dioxide
