ionic
Iron(III) chloride is an ionic compound.
It is ionic
Iron chloride (FeCl2 or FeCl3) would have to be considered as a COVALENT compound. The reason for this is that the Cl has an electronegativity (EN) value of 3.16 and Fe has an EN value of 1.83. The difference is 1.33, and it is widely accepted that to be ionic, the EN difference should exceed 1.7. Of course, iron chloride will have some ionic character, but it should more properly be classed as a polar covalent molecule. Just because it is a metal bound to a non metal, does NOT make it ionic. This is a fallacy.
No, iron and oxygen typically do not form a covalent bond. Instead, they usually form an ionic bond in compounds such as iron oxide (Fe2O3) or iron(II) oxide (FeO).
Iron and oxygen will form an ionic bond, specifically iron oxide (Fe2O3), where iron will donate electrons to oxygen to form positively and negatively charged ions that attract each other.

Iron is a metal and chlorine is a non-metal, so it would be classified as an ionic bond. However, the bond will actually possess some strong polar covalent character, because the electronegativity difference between Fe and Cl is approximately 1.2.
Iron and oxygen will form an ionic bond, specifically iron oxide (Fe2O3), where iron will donate electrons to oxygen to form positively and negatively charged ions that attract each other.
The bond between oxygen and iron in compounds such as iron oxide is considered to be predominantly ionic. Oxygen tends to gain electrons to form oxide ions, which then attract the positively charged iron ions. This results in a bond where electrons are transferred from iron to oxygen, creating an ionic bond.
Iron typically forms ionic bonds in compounds like iron(II) sulfate (FeSO4) or iron(III) chloride (FeCl3). In these compounds, iron loses electrons to become positively charged and bonds with negatively charged ions. However, iron can also form covalent bonds in certain molecules like iron pentacarbonyl (Fe(CO)5), where it shares electrons with other atoms.
FeNi is an intermetallic compound with a metallic bond. In this case, the bond between iron (Fe) and nickel (Ni) is considered metallic rather than ionic or covalent.
