101 Reactions and Equations Evidence of Chemical Reactions   The process of which the atoms of one or more substances are rearranged to form different substances is called a Chemical Reaction. DEFINITIONS AND TYPES. Revision:. DO NOT WRITE- FOR YOUR INFO ONLY. We have looked at the period table, what atoms are, elements and compounds. You have learnt that atoms can join to make compounds or molecules and that we can mix compounds to make new compounds…..these are chemical reactions. Physical Science Notes. Physical Properties. PHYSICAL PROPERTY . - A feature or characteristic of matter which can be observed without changing the identity of the matter . Examples. :. . . Color. Theme: . Changes and Reactions .
