Is iron (II) oxide ionic or covalent?
An ionic compound is neutral, so the positive and negative charges are equal. In the case of iron(II) oxide, one #"Fe"^(2+)"# ion combined with one #"O"^(2-)"# ion creates a neutral compound. #2^+ + 2^(-) = 0#.

What is Iron II Oxide?
Iron (II) oxide, pronounced as "iron two oxide," is an ionic compound. Ions are positively and negatively charged particles that are attracted to each other, forming a new substance. Iron (II) oxide can also be written as FeO, iron is Fe (Fe comes from the Latin ferrum) and oxide is oxygen with a name change because it is at the end of an ionic compound. Sometimes it is called ferrous oxide or iron monoxide.
What is the formula for iron oxide?
FeO is the molecular formula for iron (II) oxide. Because iron forms more than one cation, or positive ion, the Roman numeral II is used to distinguish it from the iron (III) cation.
Where is iron oxide found?
A German scientist named Friedrich Wust was the first person to synthesize the mineral. Wustite is part of a group of metal oxides called periclases. They have a 1:1 ratio of metal ion to oxygen ion. Wustite has an octahedral crystal lattice, like that of rock salt. Wustite can be found in a few places like Germany, Greenland, and India, as well as deep sea brines and inclusions in diamonds. On Mars, iron (III) oxide is responsible for the red soil, however, iron (II) oxide lends a dark contrast to the expanse.
What is the ratio of iron and oxygen?
The first is the ionic bond formula. There is a 1:1 ratio of iron ions and oxygen ions. The second formula represents what happens when elemental iron and oxygen are thrown together.
What is the most common element in the periodic table?
Oxygen is one of the most common elements. It is a gas at room temperature and is found in the p block of the periodic table. It normally forms a -2 anion, meaning it takes two electrons and forms a negatively charged ion. Oxygen is considered a nonmetal. When these two elements bond ionically (opposite charges attract) a whole new substance is formed. When iron (II) oxide comes into contact with water, a light blue/green crystal is formed. A similar phenomenon occurs when copper (II) sulfate and water come together; a beautiful blue crystal is formed. The water combines in the crystal structure of the compounds.

Is iron oxide a rock salt?
Iron (II) oxide adopts the cubic, rock salt structure, where iron atoms are octahedrally coordinated by oxygen atoms and the oxygen atoms octahedrally coordinated by iron atoms. The non-stoichiometry occurs because of the ease of oxidation of Fe II to Fe III effectively replacing a small portion of Fe II with two thirds their number of Fe III, which take up tetrahedral positions in the close packed oxide lattice.

What is the formula for FeO?
This means each iron atom turns into the ion Fe +2 and each oxygen atom turns into the oxide ion O -2. Since these ions are oppositely charged they attract each other giving us the formula FeO. FeO is also known as the mineral wustite. The black rocks and dirt on Mars are iron (II) oxide.
How many electrons does an oxygen atom need to fill its outer shell?
2Fe + O 2 → 2FeO. Every oxygen atom needs two electrons to fill its outer shell. One iron atom, in this case, donates two electrons to one oxygen atom. This is where the Roman numeral II comes from after iron's symbol. This means each iron atom turns into the ion Fe +2 and each oxygen atom turns into the oxide ion O -2.
