The physical world consists of an amazing variety of materials whose differences can be described in terms of their physical and chemical properties. Depending on temperature and pressure, every substance also exists in different states. What materials share in common is that they are all derived from various combinations of approximately 100 naturally occurring elements which in turn consist of different kinds of atoms. All atoms consist of a central, positively charged nucleus surrounded by a cloud of much lighter, negatively charged electrons. When the atoms of two or more substances interact to form something new the elements of which they are composed enter into new combinations. The properties of these new compounds are likely to be different from the original substances.Conceptual StrandThe composition and structure of matter is known, and it behaves according to principles that are generally understood.Guiding QuestionHow does the structure of matter influence its physical and chemical behavior?
