yes
yes it will form an ionic compound.
The chemical formula for the compound formed between iron(III) and iodine is FeI3 (iron(iii) iodide).
This compound is iron(II) iodide - FeI2.
Yes they can form ionic compounds
No. Iron chloride is a compound of iron and chlorine, nothing else.
yes
Iron could be a compound if you combined it with carbon. Then it would just be a alloy. Overall, iron is not a compound at all. It is an element.
yes it will form an ionic compound.
This compound is the iron(III) oxide, Fe2O3.
Water is a compound of hydrogen and oxygen.
The chemical formula for the compound formed between iron(III) and iodine is FeI3 (iron(iii) iodide).
Fe3Cl
This compound is iron(II) iodide - FeI2.
Chlorine is VERY reactive. Many of the compounds formed with chlorine are very dangerous. 2. I recall Asimov claiming that iron would burn (sic) in a chlorine atmosphere. After ignition of some sort I presume. I guess that, since iron(III) chloride is a real compound, that would be evidence that chlorine is reactive with iron. I know that FeCl3 will reacts exothermically in water, so that would sort of be "buring".

A compound is 2 or more elements permanently combined. Rust is a combination of iron and oxygen, both elements- into iron oxide, a compound.
