There are many elements that do not exist in nature in pure form, especially the highly reactive ones toward either end of the Periodic Table, such as sodium and chlorine. These are always derived from compounds.
Also the only metal that is found in its pure form in nature is gold due to its extreme unreactivity.
Your question hints at something but is incomplete.
Meitnerium is a synthetic element, so it does not naturally occur in compounds in the environment. However, it could potentially form compounds with elements like oxygen, fluorine, or chlorine due to its position in the periodic table. These compounds would be highly unstable and only exist in a laboratory setting.
There is no such thing as a compound element. Something cannot be both an element and a compound Neon is an element and so is made of nothing but neon. Neon does not form any compounds.
There is no compound called "sodium phosphorus." Sodium is an element with the symbol Na, while phosphorus is an element with the symbol P. These elements can combine to form various compounds, such as sodium phosphate (Na3PO4), but "sodium phosphorus" specifically does not exist.
Oxygen can exist on its own as a diatomic molecule, O2, or it can form compounds with other elements. In nature, oxygen is commonly found in both elemental form and in various compounds.
Nearly all metals will form ionic compounds with oxygen, or 'oxides', as they are called.

Aluminum is a chemical element that exists naturally in its pure form. However, in most practical applications, it is used in compounds or alloys with other elements to improve its properties and strength.

No, it is an element but as such can form compounds.
Neither, it is an ion that cannot exist on its own as a substance. It is known as the fulminate ion. It combines with positive ions to form various compounds.

Yes, they can.
Group 0 Elements ( Helium, Neon, Argon...) do not form compounds because they have a complete Octet and are thus unreactive and exist as mono atomic elements
No. Many compounds are liquids (water, hexane) and gasses (carbon dioxide, ammonia) at room temperature. Many compounds are solid at room temperature and can, but often do not exist in the form of a powder.
It is an element, it can become an ion, but it is usually just an element combined with 02 after mixing with the atmosphere.
Metals form compounds very easily with non-metals.
