For substances, composition means the constituent materials or elements. For writing or music, composition is the act of composing or creating, combining the separate elements or aspects into a whole.
No, composition and structure are not the same thing. Composition refers to the elements that make up a substance or material, while structure refers to how those elements are arranged or organized within the substance.
Chemical elements are not mixtures (I do not think to the isotopic composition).
Their chemical composition
The successful unification of the elements of art and the principles of design in an artwork.

If the composition of a material is fixed, it means that the material is made up of a set combination of elements in specific proportions. This fixed composition gives the material its unique properties and characteristics, which remain consistent as long as the composition is maintained.
Elemental composition refers to the types and relative proportions of elements present in a substance. This composition can be expressed in terms of the atomic symbols and the number of atoms of each element in the substance. It provides valuable information about the chemical properties and behavior of the substance.
The Law of Definite Composition states that a compound will always have the same proportion of elements by mass. This relates to the empirical formula because the empirical formula gives the simplest whole number ratio of the elements in a compound, which reflects the fixed composition of elements as per the Law of Definite Composition.
When 2 or more elements are not chemically joined together, it is called a mixture. Mixtures can be classified as homogeneous (uniform composition) or heterogeneous (non-uniform composition) depending on how evenly the elements are distributed.
