If all the components are made from pure copper - yes, all is from the chemical element copper.
A copper door knob is a mixture of copper and other elements or compounds that form the alloy used to make the door knob. Copper itself is an element, but when combined with other elements or compounds to form an alloy, it becomes a mixture.
it is a mixture
Metals can be elements, yes, however, most that you would see on a day to day basis i.e. cookware, door handles, etc. Most of these metals are alloys, which are a mixture of several elemental elements. For example, brass, a common door handle metal, is a mixture of zinc and copper. So, to find out the elemental metals, look at a periodic table.
i would say so because its technically a wedge and an inclined plane but others might disagree
A brass door handle is typically composed of two types of atoms: copper and zinc. Copper gives brass its characteristic reddish color and malleability, while zinc provides strength and durability.

A copper door knob is a mixture, as it is made up of a combination of copper metal and potentially other elements or compounds depending on the specific door knob design (e.g., other metals for strength or decorative finishes).
Both are mixtures.

Red paint on a door is a mixture. It typically consists of various pigments, binders, solvents, and additives, which are combined to create the final product. Each component retains its own properties, making the paint a heterogeneous mixture rather than a pure substance like an element or a compound.
A brass door knob is a mixture, specifically an alloy composed primarily of copper and zinc. The properties of brass can vary depending on the proportions of these metals, but it does not have a fixed chemical composition, which characterizes mixtures. In contrast, a compound would have a definite chemical formula and consistent properties. Thus, brass is classified as a mixture rather than a compound.
A brass doorknob is a mixture, specifically an alloy, primarily composed of copper and zinc. It contains varying proportions of these metals, which give brass its characteristic properties, such as strength and corrosion resistance. As a mixture, the individual components retain their distinct properties and can be separated through physical means.
Doors vary in composition and are rarely composed of a single element. Many doors are made of wood, which is not an element but a mixture of compounds. The primary component is cellulose, a compound of carbon, hydrogen, and oxygen. Doors may also be made of various metals such as aluminum, iron, steel (a mixture of iron, carbon, and possibly other metals), and galvanized metal (metal coated with a layer of zinc).
Door is not a compound word.

A compound word that contains the word door is doorbell.
