What are non stochiometric compounds?
A non stoichiometric compound is one where an exact integer ratio of atoms is not achieved. An example is FeO- all laboratory specimens are "iron deficient" with formals of about Fe0.8 O this is a feature of non -stoichiometric compounds their composition is variable within narrow limits- some of the iron is Fe3+, the crystal lattice has "defects" that accomodate them. (Pure FeO can be made but it is pyrophoric (may spontaneously in flame)
Is Cerium Oxide Ferrous or Non-Ferrous?
Cerium oxide is non ferrous, as it does not contain any iron.
What are non -stoichiometric compounds?
Non-stoichiometric compounds are compounds that do not have a fixed ratio of elements in their chemical formula. This means that the ratio of elements in the compound can vary within certain limits. This can be due to factors such as defects in the crystal lattice or the presence of excess or deficient elements in the compound.
Why FeO is non-stoichiometric?
Ferrous oxide is non-stoichiometric because Fe2+ is readily oxidised to Fe3+. A lattice forms with some Fe3+ replacing Fe2+ (2 Fe3+ replace on average 3Fe2+ ) The lattice structure can accomodate a small degree of "distortion" and the net result is a compound sample with a composition Fe0.95O.
Is fe2o3 a metalloid?
No, metalloids are elements, Fe2O3 is a compound known as iron III Oxide

What is a berthollide?
A berthollide is any non-stoichiometric compound.

Where can you buy small amounts of ferous oxide?
Iron(II) oxide, also known as ferrous oxide or informally as iron monoxide, is one of the iron oxides. It is a black-colored powder with the chemical formula FeO. It consists of the chemical element iron in the oxidation state of 2 bonded to oxygen. Its mineral form is known aswüstite. Iron(II) oxide should not be confused with rust, which usually consists of hydrated iron(III) oxide (ferric oxide). The term may be used more loosely for a non-stoichiometric compound as the ratio of the elements iron and oxygen can vary; samples are typically iron deficient with compositions ranging from Fe0.84O to Fe0.95O.[2]
Why FeO is non-stoichiometric?
Ferrous oxide is non-stoichiometric because Fe2+ is readily oxidised to Fe3+. A lattice forms with some Fe3+ replacing Fe2+ (2 Fe3+ replace on average 3Fe2+ ) The lattice structure can accomodate a small degree of "distortion" and the net result is a compound sample with a composition Fe0.95O.
Is fe2o3 a metalloid?
No, metalloids are elements, Fe2O3 is a compound known as iron III Oxide
Is iron oxide ionic or covalent?
Iron oxide is an ionic compound because it is composed of a metal (iron) and a non-metal (oxygen). Ionic bonds form when electrons are transferred from the metal to the non-metal, resulting in charged ions that are held together by electrostatic attraction.
What happen to iron when it rusts?
Iron is oxidised when it turns to rust. The iron atoms lose electrons forming Iron(III) ions, which form a non-stoichiometric compound with oxygen and hydroxide ions and water. Rust is a much weaker substance than iron, and very crumbly, so iron loses its strength and may crumble away.
When a metal reacts with a non metal it makes what?
It forms a compound. For example Iron + Oxygen ---> Iron Oxide aka rust.
Is beryllium oxide a non metal?
Beryllium oxyde (BeO) is a chemical compound, not a metal or a nonmetal.
What are non-stoichiometric defects?
Non stoichiometric compounds do not match to law of definite proportions.
