Each element is unique in terms of reactivity. Most elements react readily in high temperatures, but some react quicker in the cold. The same tendency is observed in respect to pressure, with most elements reacting as pressure increases. However, some others react as pressure decreases. In terms of internal factors, a higher surface area correlates with greater reactivity because reagents have a greater chance of making contact with the substance.
All substances have mass and therefore must be composed of atoms. These atoms and how they assemble themselves in the substance determines their chemical and physical properties. Substances can be classified according to how these atoms are assembled and is known as Classification of Matter: All matter falls into one of three categroies: elements, compounds or mixtures. Furthermore, mixtures can be classified as homogeneous or inhomogeneous.
