no they are not
Gold, Silver, Oxygen, and Hydrogen are not compounds because they are all elements.Sources- Science book. ^_^P.S- This better have helped!
The overall definition that includes mixtures, compounds, and elements is matter. Matter refers to anything that has mass and takes up space. Mixtures are combinations of different substances that can be physically separated, compounds are substances composed of two or more elements chemically bonded, and elements are pure substances composed of only one type of atom.
Pure elements are found least in nature compared to compounds and mixtures. Most elements exist bonded to other elements to form compounds or mixed with other substances to form mixtures in nature. Pure elements are less common due to their tendency to react and combine with other elements.
Well, elements and compounds are pure substances. This is because the atoms in an elements are of one type only. Thus making it pure. But in a compound, the ratio of the masses of the combining elements or compounds are fixed. For example, the ratio for hydrogen and oxygen to combine together to form water is 1:8. Therefore the compound is also a pure substance. But homogenous mixtures are not pure substances as the components can be mixed in any ratio. We can make brine solution by mixing any amount of salt and water. There is no fixed ratio. So homogenous mixtures are not pure.
"Pure" generally implies that the object has no unwanted material. It can include mixtures and solutions. For example, Ivory soap is advertised as being 99.9% pure meaning it has nothing in it that they didn't intend to put in the soap.
Some people divide matter into pure substances and mixtures. Pure substances are elements and compounds. Mixtures include homogeneous and heterogeneous mixtures. Some people divide matter into homogeneous matter and heterogeneous matter. Homogeneous matter includes pure substances and homogeneous mixtures (solutions). Heterogeneous matter is heterogeneous mixtures.
Pure matter substances can be elements, compounds, or mixtures where all components are the same throughout. Examples include pure water (H2O), pure iron (Fe), and pure table salt (NaCl).

whyMatter can be broken down into Pure Substances and Mixtures. Mixtures can't be broken down by anything, however Pure Substances break down to Elements and Compounds.The mixtures whether it is homogenous or heterogoneous can NOT be broken down and be observed because it is a chemical change not a physical change
Matter is classified as mixtures and substances. Mixtures are composed of two or more different substances that are physically combined, while substances are pure forms of matter that cannot be separated by physical means. Substances are further divided into elements and compounds.
Pure elements cannot be mixtures.
Most substances around us are mixtures, rather than pure substances. Mixtures are composed of two or more substances that are physically combined and can be separated by physical means, while pure substances are made up of only one type of particle. Examples of mixtures include air, sea water, and soil.
They are actually elements so that is pure substances. Mixtures are more than one type of element that are in the same space but not touching. Compounds are like mixtures but they are touching.
Neon is a pure substance. Elements and compounds are pure substances; mixtures are not.
Matter is classified into two main categories: pure substances and mixtures. Pure substances are further divided into elements and compounds, while mixtures are divided into homogeneous and heterogeneous mixtures.
Mixtures
Pure substances (elements and compunds) and mixed substances (mixtures, solutions, alloys).
