oxyde d'uranium
Rust is iron oxyde - Fe2O3, not a polymer.
Yes, calcium oxyde - CaO.
Water is a compound, an oxyde of hydrogen - H2O.
Heleum oxyde
you mean nitrous oxyde, right?
Water is an oxyde of hydrogen, a polar molecule.
Liquid water is an oxyde of hydrogen; the chemical formula is H2O.
The correct spelling of the chemical term is "oxide" (containing atoms of oxygen).
An object that suffered oxidation, had its atoms reacted with the O² present on the air and in the water. This happens when a bar of iron oxyde for being in a humid place. The molecular equation for the oxidation of the iron bar is like this: Fe + H²O = FeO + H²
Actinium is found in very low concentrations in uranium ores, probably as an oxyde.
Uranium is radioactive and toxic. The risk is dependent from the chemical form (oxyde, solution, metal, fluorides, etc.), physical form (metal, sintered oxyde, powders, aerosols, liquids), enrichment, irradiated or not; also importants are the radioactive descendents of uranium, especially the gas radon.
