of atoms. (2) Atoms of an element are alike. (3) Atoms of different elements are different. (4) Atoms of different elements join together to make compounds. In the late 1800’s, J. J. Thomson discovered that atoms were made of smaller particles. He discovered the electron and devised ...
aFurthermore, different chemical elements have different spectra. They absorb and reflect spectral energy differently. Different elements are combined to form compounds. Each compound has a unique spectrum due to its unique molecular structure. This is the basis for the application of spectroscopy to ...
Mixtures Most matter in the universe is found in mixtures. A mixture is made from two or more substances either elements, compounds or both - that are not chemically combined. Mixtures and compounds differ in two ways… Substances in a mixture keep their individual properties. Parts of a mixtu...
