how can chromium form two diffrent compounds with oxygen?
well some compounds including baking soda,are composed of more than two elements because theycontain polyatomic ions.
( answered question bye veronica wilson:)
No. Chlorine an oxygen will form covalent compounds.
Cr2O3 is usually considered to be an ionic compound, in which instance its proper name is "chromium (III) oxide" (now preferred) or "chromic oxide" (more often used about 50 years ago.) If Cr2O3 is considered to be covalently bonded, its proper systematic name would be "dichromium trioxide." Some chemists also call it "chromic acid anhydride."
both. the chromium metal would form an ionic bond, and chromium nitrate is molecular because it contains atoms of different elements.
Iron can form two different ions, Fe2+ and Fe3+. Because of their different charges these ions will bond differently with anions such as oxide (O2-) As a result we get the compounds FeO and Fe2O3. There is a third oxide which is a combination of the two: Fe3O4
Nearly all metals will form ionic compounds with oxygen, or 'oxides', as they are called.
Because chromium is a plurivalent chemical element; four oxides are known today: CrO2, CrO3, Cr2O3, Cr3O4.
Nonmetals burning in oxygen form covalent type compounds, as compared to metals which form ionic compounds.
yes. If the metal is reactive enough then oxygen naturally forms compounds.(oxides)
Oxygen and chlorine are each elements, not compounds. They combined to form a number of covalent compounds because they are both nonmetals.
No. Chlorine an oxygen will form covalent compounds.
ionic and covalent compound
Up today are known compounds of einsteinium with oxygen and halogens.

No, iron is an element. Chrmium is also an element, so there are no other substances, compounds or otherwise, that are found in it. However, there are alloys that contain both iron and chromium along with other metals.
thanks folks!
(Two or more than two ) Atoms or molecules of different elements combine to form compounds, like: Hydrogen(atom) and Chlorine combine to form HCL (an acid) Hydrogen(molecule) and oxygen combine to fom H2O (water)
both. the chromium metal would form an ionic bond, and chromium nitrate is molecular because it contains atoms of different elements.
