Lecture Campbell biology (9th edition) - Chapter 2: The chemical context of life. This chapter presents the following content: Matter consists of chemical elements in pure form and in combination called compounds, an element's properties depends on the structure of its atoms, the formation and function of molecules depend on chemical bonding between atoms, chemical reaction make and break chemical bonds. | The Chemical Context of Life Chapter 2 Concept : Matter consists of chemical elements in pure form and in combinations called compounds Organisms are composed of matter Matter is anything that takes up space and has mass © 2011 Pearson Education, Inc. Elements and Compounds Matter is made up of elements An element is a substance that cannot be broken down to other substances by chemical reactions A compound is a substance consisting of two or more elements in a fixed ratio A compound has characteristics different from those of its elements © 2011 Pearson Education, Inc. Figure Sodium Chlorine Sodium chloride Figure The emergent properties of a compound. The metal sodium combines with the poisonous gas chlorine, forming the edible compound sodium chloride, or table salt. The Elements of Life About 20–25% of the 92 elements are essential to life Carbon, hydrogen, oxygen, and nitrogen make up 96% of living matter Most of the remaining 4% consists of calcium, .
