SteveStoichiometric solids have a fixed and constant ratio of elements, while non-stoichiometric solids have variable ratios due to defects in the crystal lattice. Stoichiometric solids follow the laws of definite proportions, whereas non-stoichiometric solids can exhibit a range of compositions within the same material.

Is iron oxide a non stoichiometric compound?
Yes, iron oxide can exist as a non-stoichiometric compound. This means that the ratio of iron to oxygen atoms in the compound is not a whole number and can vary. Examples include magnetite (Fe3O4) and wüstite (FeO).
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.
Which of the solids and liquids are non-polar?
Solids: Examples of non-polar solids include wax and plastic. Liquids: Examples of non-polar liquids include hexane and toluene.
What are non stochiometric compounds?
Non-stoichiometric compounds are compounds that do not have a fixed ratio of elements. This means that the actual composition of the compound can vary, leading to a range of possible formulas. Examples include transition metal oxides like Fe3O4 or copper oxide (Cu2O), which can have variable oxidation states resulting in non-stoichiometric compositions.
What is the difference between crystalline and non-crystalline solids?
Crystalline solids have an ordered structure with a repeating pattern of atoms or molecules, resulting in well-defined faces and sharp melting points. Non-crystalline solids, also known as amorphous solids, lack a regular arrangement of particles and do not have a distinct melting point, instead softening gradually over a range of temperatures.
