No they are not.
No, elements are the most basic form of a substance, thus mixtures might be made up from different elents but elements can never be made from mixtures.
Mixtures. In mixtures, the elements or compounds are physically combined and can be separated through physical means such as filtration or distillation.
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.
A mixture is composed of two or more substances that are not chemically combined. Elements themselves, such as oxygen, gold, or iron, are pure substances and cannot be mixtures. However, mixtures can contain various elements, such as air (a mixture of gases like nitrogen and oxygen) or alloys (like bronze, which is a mixture of copper and tin). Thus, while elements themselves are not mixtures, they can be components of various types of mixtures.
Pure elements cannot be mixtures.
Chemical elements are not mixtures (I do not think to the isotopic composition).
Yes, all the mixtures contain compounds or elements.
No, they are mixtures.

In Plato's theory of elements, earth and water are considered to be mixtures of his four elements. Earth is a combination of earth and water, while water is a combination of water and air. These mixtures are seen as intermediate states between the pure elemental forms, representing a blending of qualities from the primary elements. Plato believed that these mixtures played a crucial role in the physical world and the composition of all material substances.

Yes. Everything is composed of elements.
