Campbell's Biology, 9e (Reece et al.) Chapter 2 The Chemical Context of Life This chapter presents basic chemical principles for understanding the chemical context of living organisms, from atomic structure to the nature of chemical bonds and an introduction to chemical equilibrium. These questions focus on elements most important to life or the study of life, including the elements that comprise organic molecules and important trace elements. Some isotopes are important in geologic dating and in biological tracer studies. How elements participate in forming different types of chemical bonds is essential to mastering subsequent topics on the behavior and properties of biological molecules, structures, and energy metabolism.

Atomic Structure Definitions ? Acceleration ? The stage of mass spectrometry during which the movement of the ions of the sample is speeded up using a series of negatively-charged plates. ? Atomic number ? The number of protons in the nucleus of an atom of an element. Represented by the symbol Z. Also called the proton number. ? Deflection ? The stage of mass spectrometry during which the beam of ions is bent by a particular amount, depending on its mass-to-charge ratio. This is achieved using an electromagnet. ? Detection ? The stage of mass spectrometry during which the ions strike a collector plate, producing a mass spectrum for analysis. ? Diatomic ? A molecule consisting of two atoms. ? Electromagnet ? The part of a mass spectrometer responsible for the

Chapter 6-Chemistry in Biology COMPOSITION OF MATTER -Matter-everything in universe is composed of matter. -Matter is anything that occupies space or has mass -Mass-quantity of matter in an object -Weight-pull of gravity on us ELEMENTS -Pure substances that cannot be broken down chemically into simpler kinds of matter -More than 100 elements (92 naturally occuring) -90% of the mass of an organism is composed of 4 elements (oxygen, carbon, hydrogen, and nitrogen) -Each element has a unique chemical symbol -Consists of 1-2 letters -First letter is always captialized ATOMS -The simplest particle of an elemetnt that remains all the properties of that element. -Properties of atoms determine the structure and properties of the matter they compose.

Useful Element Notations The number of protons in the nucleus Determines the identity of the atom (which element it is) Atomic Number (Z) If you change the number of protons, the atom changes to another element. The total number of particles in the nucleus?protons and neutrons The total number of particles that make up the mass of the atom Mass Number (A) Atoms of an element which have various amounts of neutrons but the same number of protons Isotopes: Since the number of neutrons changes, the mass of the isotopes is different. Count Those Neutrons It shows the mass number, atomic number, and symbol for the element. Isotopic Notation X A Z Isotopic Notation Example: Be 9 9 protons and neutrons 9 4 4 4 protons Therefore, there must be 5 neutrons. 18 40 22 58 Question

The Development of Atomic Models: A Historical Perspective 1 Model of an Atom An IDEA of what it looks like (a working representation) 2 Atomic Models Democritus? Idea An object CANNOT be divided indefinitely. There is a smallest particle. atom: (Gk. atomos?indivisible) 3 Democritus ? Chemistry textbook p. 73 (BJU Press) Atomic Models There is a basic unit of matter?the atom. Chemists found this out by looking at the mass ratio of substances. But the atom is NOT indivisible. Democritus? Idea was CORRECT! 4 Democritus ? Chemistry textbook p. 73 (BJU Press) Continuous: Matter can be subdivided forever. Particulate: A smallest particle exists. 2 Theories Atomic Models 9 grams of H2O: 8 grams of oxygen 1 gram of hydrogen Ratio is 8:1 Mass Ratio 90 grams of H2O:
