All of these metals are solid uniform mixtures EXCEPT gold. Gold is an element because it only consists of one type of atom which is called Aurum (Au).
Solid uniform mixtures are under homogeneous mixtures. A homogeneous mixture is a solid, liquid, or gaseous mixture with a fixed composition. It means that when we sample the homogenous mixture, the amount and type of components that its made up of will always be the same.
A homogeneous mixture displays the following properties:
A homogeneous mixture is made up of only one phase. It only consists of a solid, liquid, or gas.
While the mixture's components retain their chemical identities, they are not visibly different. However, the mixture includes multiple compounds or elements at the molecular level.
The compositions and characteristics of samples collected from different parts of the mixture are identical.
A mechanical process such as filtration is normally not effective for separating components of a homogenous mixture.
Samples of solid homogenous mixtures:
Brass - an alloy that is made with copper and zinc.
Bronze - is a copper-tin alloy; bronze is a type of alloy, which is a metal made up of two or more metallic components.
Steel - is an iron-carbon alloy; both steel and stainless steels, which contain chromium, are homogenous mixtures.
Samples of liquid homogenous mixtures:
Wine - wine, like all liquors is based on using ethanol and/or water as a solvent on different substances to create different flavors.
Water - all water contains dissolved minerals and gases except for pure water; These minerals and gases are dissolved all throughout the water.
Coffee - a homogeneous mixture of water and filtered coffee granules.
Samples of gaseous homogenous mixtures:
Air - a mixture of oxygen, nitrogen, argon, and carbon dioxide and a little more quantities of some elements.
Natural gas - a mixture of methane and other hydrocarbons that is being used as a fuel.
