What is a non - metal plus oxygen?

A non-metal element(s) plus oxygen is a covalent compound. The element or elements bond(s) covalently with oxygen. The process by which this happens may be called combustion if oxygen acts as an oxidizer and the other acts as the fuel or reducer. Some examples: H2O - Dihydrogen Monoxide (Water) CO - Carbon Monoxide CO2 - Carbon Dioxide SO2 - Sulfur Dioxide SO3 - Sulfur Trioxide N2O - Nitrous Oxide OF2 - Oxygen Difluoride P2O5 - Phosphorus Pentoxide Here is a list of all known oxides, metal and nonmetal: * Element in -1 oxidation state ** Oxygen difluoride (OF2) * Element in multiple oxidation states ** Antimony tetroxide (Sb2O4) ** Cobalt(II,III) oxide (Co3O4) ** Iron(II,III) oxide (Fe3O4) ** Lead tetroxide (Pb3O4) ** Manganese(II,III) oxide (Mn3O4) ** Silver(I,III) oxide (AgO) * Element in +1 oxidation state ** Copper(I) oxide (Cu2O) ** Dicarbon monoxide (C2O) ** Dichlorine monoxide (Cl2O) ** Lithium oxide (Li2O) ** Potassium oxide (K2O) ** Rubidium oxide (Rb2O) ** Silver(I) oxide (Ag2O) ** Thallium oxide (Tl2O) ** Sodium oxide (Na2O) ** Water (hydrogen oxide) (H2O) * Element in +2 oxidation state ** Aluminium monoxide (AlO) ** Barium oxide (BaO) ** Beryllium oxide (BeO) ** Cadmium oxide (CdO) ** Calcium oxide (CaO) ** Carbon monoxide (CO) ** Cobalt(II) oxide (CoO) ** Copper(II) oxide (CuO) ** Iron(II) oxide (FeO) ** Lead(II) oxide (PbO) ** Magnesium oxide (MgO) ** Mercury(II) oxide (HgO) ** Nickel(II) oxide (NiO) ** Nitrogen oxide (NO) ** Palladium(II) oxide (PdO) ** Strontium oxide (SrO) ** Sulphur monoxide (SO) ** Tin(II) oxide (SnO) ** Titanium(II) oxide (TiO) ** Vanadium(II) oxide (VO) ** Zinc oxide (ZnO) * Element in +3 oxidation state ** Aluminium oxide (Al2O3) ** Antimony trioxide (Sb2O3) ** Arsenic trioxide (As2O3) ** Bismuth trioxide (Bi2O3) ** Boron oxide (B2O3) ** Chromium(III) oxide (Cr2O3) ** Dinitrogen trioxide (N2O3) ** Erbium(III) oxide (Er2O3) ** Gadolinium(III) oxide (Gd2O3) ** Gallium(III) oxide (Ga2O3) ** Holmium(III) oxide (Ho2O3) ** Indium(III) oxide (In2O3) ** Iron(III) oxide (Fe2O3) ** Lanthanum(III) oxide (La2O3) ** Lutetium(III) oxide (Lu2O3) ** Nickel(III) oxide (Ni2O3) ** Phosphorus trioxide (P4O6) ** Promethium(III) oxide (Pm2O3) ** Rhodium(III) oxide (Rh2O3) ** Samarium(III) oxide (Sm2O3) ** Scandium(III) oxide (Sc2O3) ** Terbium(III) oxide (Tb2O3) ** Thallium(III) oxide (Tl2O3) ** Thulium(III) oxide (Tm2O3) ** Titanium(III) oxide (Ti2O3) ** Tungsten(III) oxide (W2O3) ** Vanadium(III) oxide (V2O3) ** Ytterbium(III) oxide (Yb2O3) ** Yttrium(III) oxide (Y2O3) * Element in +4 oxidation state ** Carbon dioxide (CO2) ** Carbon trioxide (CO3) ** Cerium(IV) oxide (CeO2) ** Chlorine dioxide (ClO2) ** Chromium(IV) oxide (CrO2) ** Dinitrogen tetroxide (N2O4) ** Germanium dioxide (GeO2) ** Hafnium(IV) oxide (HfO2) ** Lead(IV) oxide (PbO2) ** Manganese(IV) oxide (MnO2) ** Nitrogen dioxide (NO2) ** Plutonium dioxide (PuO2) ** Ruthenium(IV) oxide (RuO2) ** Selenium dioxide (SeO2) ** Silicon dioxide (SiO2) ** Sulfur dioxide (SO2) ** Tellurium dioxide (TeO2) ** Thorium dioxide (ThO2) ** Tin dioxide (SnO2) ** Titanium dioxide (TiO2) ** Tungsten(IV) oxide (WO2) ** Uranium dioxide (UO2) ** Vanadium(IV) oxide (VO2) ** Zirconium dioxide (ZrO2) * Element in +5 oxidation state ** Antimony pentoxide (Sb2O5) ** Arsenic pentoxide (As2O5) ** Dinitrogen pentoxide (N2O5) ** Niobium pentoxide ** Phosphorus pentoxide (P2O5) ** Tantalum pentoxide (Ta2O5) ** Vanadium(V) oxide (V2O5) * Element in +6 oxidation state ** Chromium trioxide (CrO3) ** Molybdenum(VI) oxide (MoO3) ** Rhenium trioxide (ReO3) ** Selenium trioxide (SeO3) ** Sulphur trioxide (SO3) ** Tellurium trioxide (TeO3) ** Tungsten trioxide (WO3) ** Uranium trioxide (UO3) ** Xenon trioxide (XeO3) * Element in +7 oxidation state ** Dichlorine heptoxide (Cl2O7) ** Manganese(VII) oxide (Mn2O7) ** Rhenium(VII) oxide (Re2O7) ** Technetium(VII) oxide * Element in +8 oxidation state ** Osmium tetroxide (OsO4) ** Ruthenium tetroxide (RuO4) ** Xenon tetroxide (XeO4)
