An alloy is a homogeneous mixture

Wiki User. An alloy is considered a homogeneous mixture because by definition, a homogeneous mixture has the same uniform appearance and composition throughout. Since an alloy is a mixture of two or more metals, or a mixture of a metal with some other element, and these mixtures are uniform throughout, they fit the definition of being homogeneous. Gold is very inert.

An alloy is a homogeneous mixture

An alloy is a homogeneous mixture of two elements, with one being a metal solid. For example, Gold as used in jewelry is usually a mixture of gold, silver, and some other metals. When these metals are melted and mixed up, they form alloys. A sample of the new gold alloy will have the same chemical make up like any other sample of that new gold alloy. Atomic arrangement in alloys is very irregular and different in sizes, making it harder for its layers to slide over each other. Stainless steel behaves in a similar way. It is also a mixture of Iron, Chromium, and Nickel. These metals mix up perfectly to become alloys too. The advantage of this mixture is that the alloy tends to have better qualities than the original. For example, an alloy of gold would have better properties in terms of its strength and luster than the unmixed gold. Amalgam is one common alloy. It is used often by dentists to fill cavities in teeth. The main metal in amalgam is mercury.

An alloy is a substance made by combining together two or more elements where the primary element is a metal. Most alloys form by melting the elements together. Upon cooling, an alloy crystallizes into a solid, intermetallic compound, or mixture that cannot be separated using a physical method. Although an alloy may contain metalloids or nonmetals, it displays the properties of a metal. The primary metal in an alloy is called its base, solvent , or matrix. Secondary elements are called solutes. Undesirable elements are called impurities. If the alloy consists of only two elements, the result is a binary alloy. If three elements, the result is a ternary alloy.

An alloy is a homogeneous mixture

A homogeneous mixture is a solid, liquid, or gaseous mixture that has a uniform composition. No matter where you sample the mixture, the amount and type of components is the same. Any chemical solution or alloy is a homogeneous mixture. Examples of solutions include sugar water and powdered drink mix in water, while alloys include sterling silver and bronze.
