Answer:
Iron (II) oxide
Step-by-step explanation:
Chemical formula of the given compound = FeO
The given compound is an oxide.
In oxides, oxidation state of 'O' is -2.
Let oxidation state of Fe be x. It is a neutral compound.
Therefore, x - 2 = 0
x = +2
So, the oxidation state of Fe in FeO = +2
In the nomenclature of inorganic compounds, cation is named first. After that oxidation state of cation is written. Name of anion is written after that.
Cation = Iron
Anion = oxide
So the name of the given compound would be Iron (II) oxide.
