What is a Compound? - A compound is a chemical substance can be broken down into two or more simpler substances. A chemical element that makeup compounds by combining with each other elements in definite proportions. Learn about Elements and Compounds Examples Here.
A compound contains atoms of different elements, chemically joined together. Compounds form in chemical reactions, and you need other chemical reactions to separate a compound into its...

Key Points. Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.
Mixtures are physical combinations of two or more elements and/or compounds. Mixtures can be classified as homogeneous or heterogeneous. Elements and compounds are both examples of pure substances.
A compound is a pure substance which contains identical molecules with two or more types of atomic core. A mixture is a material which has two or more types of molecules. Clearly, these definitions only apply to molecular materials, and will need to be extended to ionic and metallic materials later.
