Iron is not a compound, it is a metallic element.
Ionic
It is an ionic compound.
No, FeO2 is not an ionic compound. It is more likely a covalent compound based on the elements it consists of (iron and oxygen). Iron can form both ionic and covalent compounds, but in the case of FeO2, it is more likely covalent due to the high oxidation state of oxygen.
Iron(III) chloride is an ionic compound.
Fe3N2 is ferric nitride, and it is ionic, not covalent.
Iron sulphide is an ionic compound. The Iron is in a +2 oxidation state and the sulphur is in a -2 oxidation state.
Yes it is an ionic compound because it is form between Fe (iron) and CO3 (carbonate).
It is ionic
Iron bromide is an ionic compound. Iron typically forms ionic compounds with nonmetals like bromine by transferring electrons to achieve a stable configuration.
Chlorine oxide would be a covalent compound, and not an ionic compound.
is carbon an tretaflouride ionic or covalent compound
Electronegativity Fe = 1.83; O = 3.44 3.44 - 1.83 = 1.61 Since the electronegativity difference is 1.61 the bond is polar covalent 0 - 0.4 = Pure Covalent Bond 0.41 - 1.7 = Polar Covalent Bond 1.7 + = Ionic Bond
