No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.
Compounds are composed of atoms of different elements chemically bonded in definite proportions. The components of mixtures are not chemically combined and they do not have definite proportions.
Compounds are composed of two or more elements that are chemically combined in definite proportions. The elements in a compound are held together by chemical bonds, which result in a unique set of properties different from the elements that make up the compound.
