Why alloys are not mixtures?

Answer 1

Because it is a natural metal, in other word, it is a primary metal, like iron, gold, silver. To be part of an alloy it must be melted with zinc, or other metals.

Answer 2

An Alloy is not classed as a compound because no chemical reaction has taken place.

Copper and zinc can be melted down and mixed to make brass. Even though brass has different properties to iron and zinc you cannot break it down into a single molecule of brass. There is no such thing as a brass molecule.

Answer 3

An alloy is a substance composed of two or more elements, at least one is a metal.

Generally alloys have metallic properties. If you want to make an alloy, you can add any element to a metal. Then it can form a solid solution or compound based on the valence rules. Compound is a phase which comes as a sub classification of an alloy. Further more, an alloy is based on metals. A compound can have any two metals as their components. For example, H2O is a compound but not an alloy.

Answer 4

In alloy the metals and non-metals do not chemically react with each other and there is just a physical mixture of different element and to have a compound it is necessary to form chemical bonds so that is why alloy are not compounds

Answer 5

Alloying two elements, as in the alloy "steel" of iron and carbon, involves combining them (not bonding, however). In steel, they do not simply exist separately as oil and water would. This oil/water example would be an example of a true mixture.

Answer 6

Alloys are not considered mixtures because they are composed of a single phase with a uniform distribution of atoms. In alloys, the elements are mixed at the atomic level leading to the formation of a new material with unique properties, unlike mixtures where the components remain distinct.

Answer 7

No, An alloy is just a physical mixture of two elements in which they don't chemically react to form compounds.

Answer 8

the atoms in an alloy are not bonded they are just in a solid mixture,

e.g. iron + carbon = steel

Answer 9

There is no necessary constant proportion between or among elements in an alloy. Such proportionality is a characteristic of a chemical compound.
