Iron is bonded to six oxygen ligands.
When oxygen is bonded to a metal, it forms an oxide compound. When oxygen is bonded to a nonmetal, it forms an oxide compound as well. Oxygen can form both ionic and covalent bonds with different elements depending on their electronegativity.
The main compound found in haematite is iron(III) oxide, which is chemically represented as Fe₂O₃. Haematite is one of the primary ores of iron and is characterized by its reddish-brown color. It plays a significant role in the production of iron and steel.
Also, possible you think to an alloy.
Metallic oxides are metal and oxygen, bonded together. They are generally solids, and have higher densities. An example of a metallic oxides is sodium, Na.
Bromine only conducts electricity when bonded with another metal/element.
Iron is extracted from haematite.

Haematite is a form of iron(III) oxide, Fe2O3, which is found in the Earth's crust.

Haematite is another name for iron ore. The prefix 'Haem' comes from Classical Greek for iron. Compare with the Latin for iron , which is 'Ferrum' (Fe). Haematite is an oxide of ioron. So by smelting, iron ore was reduced to iron. So the metal in haematite is IRON. Compare with the biological name 'haemaglobin', part of the blood in humans. The 'haem' moiety indicates the 'iron' ion. Or the word ' **Haematuri**a', This is a medical term , for blood in the urine stream.
No. Carbon dioxide is a covalently bonded compound that is very different from a metal.
The oxidation of a metal produces a metal oxide. For example, calcium + oxide -> calcium oxide
Hematite is not made from calcium carbonate.
Hematite is a mineral made of iron and oxygen. It can be gray, red, or brown.
They are formed when a strong metal atom is bonded with a strong non metal atom.
You are thinking of the ammonium radical, NH4-.
