If all the components are made from pure copper - yes, all is from the chemical element copper.
Element
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.
Brass is an alloy of copper and zinc that keeps its shape even when hit hard
i would say so because its technically a wedge and an inclined plane but others might disagree

Copper (Cu) is a chemical element.
Both are mixtures.

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.
No, it is not.
I only know one soz and the compound word that starts with door is doormat
No, copper is too soft and maleable to be used for something like a door know. The most common metal for doorknobs is brass which is an alloy of copper and zinc
