  1. Professor’s eyes only… You may be surprised to learn… …that over 25% of all undergraduate students do not utilize their required course material. …student retention is dropping nationwide and while the higher education community has done a remarkable job of opening the doors of college to more and more students, we have not seen equal strides in the number of students who actually complete four-year degrees.(Education Trust, 2004) See the next slide on what you can do… Professor: Course/Section:

  2. Professor’s eyes only… • What you can do… • The top factors motivating a student to use their adopted books all involve whether the material is immediately used, referred to, or assessed from in the classroom. • Please take a few minutes the first day of class to explain and demonstrate why you adopted your book and accompanying technology. • The next few slides show the book, technology products, and messaging to students that indicates they will be responsible for the content. Feel free to customize the information or delete from your slide set. Professor: Course/Section:

  3. Solomon/Berg/MartinBiology, 8e This is your required course material You will need this material for: - tests and quizzes - homework and reading assignments Professor: Course/Section:

  22. Atoms and Molecules: The Chemical Basis of Life Chapter 2

  23. Learning Objective 1 • What principal chemical elements are found in living things? • What are the most important functions of these elements?

  24. Element • A substance that cannot be decomposed into simpler substances by normal chemical reactions

  25. The Periodic Table

  26. KEY CONCEPTS • Carbon, hydrogen, oxygen, and nitrogen are the most abundant elements in living things (about 96% of mass)

  27. Element Functions • Carbon • backbone of organic molecules • Hydrogen and oxygen • components of water • Nitrogen • component of proteins and nucleic acids

  28. Learning Objective 2 • Compare the physical properties (mass and charge) and locations of electrons, protons, and neutrons • What is the difference between the atomic number and the mass number of an atom?

  29. Atom • Nucleus • protons (positive) • neutrons (uncharged) • Electrons • encircle the nucleus • negative

  30. Atomic Number and Mass • Each atom is a particular element • identified by number of protons (atomic number) • Atomic mass • sum of protons and neutrons

  31. AMU • Atomic Mass Unit • Mass of a single proton or neutron • Mass of an electron • about 1/1800 amu

  32. Isotopes

  33. Carbon-14 (14C) (6p, 8n) 6 Carbon-12 (12 C) (6p, 6n) 6 Fig. 2-2, p. 28

  34. Learning Objective 3 • What are orbitals and electron shells? • How are electron shells related to principal energy levels?

  35. KEY CONCEPTS • Chemical properties of an atom are determined by its highest-energy (valence) electrons

  36. Orbitals • Electrons move rapidly in electron orbitals • Outside the nucleus • Electron shell • Electrons in orbitals at the same principal energylevel • Electron in shell far from nucleus has more energy than electron in shell close to nucleus

  37. Atomic Orbitals

  38. Nucleus (a) The first principal energy level contains a maximum of 2 electrons, occupying a single spherical orbital (designated 1s). The electrons depicted in the diagram could be present anywhere in the blue area. Fig. 2-4a, p. 30

  39. (b) The second principal energy level includes four orbitals, each with a maximum of 2 electrons: one spherical (2s) and three dumbbell-shaped (2p) orbitals at right angles to one another. Fig. 2-4b, p. 30

  40. (c) Orbitals of the first and second principal energy levels of a neon atom are shown superimposed. Note that the single 2s orbital plus three 2p orbitals make up neon's full valence shell of 8 electrons. Compare this more realistic view of the atomic orbitals with the Bohr model of a neon atom at right. Fig. 2-4c, p. 30

  41. Learning Objective 4 • How does the number of valence electrons of an atom relate to its chemical properties?

  42. Valence Electrons • Electron in the outer shell • most energetic electrons • Number and arrangement of an atom’s valence electrons • determine its chemical properties

  43. Valence Electrons • An atom tends to lose, gain, or share electrons to fill its valence shell • Electrons needed to fill valence shell • Most atoms: 8 electrons • Hydrogen or helium: 2 electrons

  44. Learning Objective 5 • What is the difference between simplest, molecular, and structural chemical formulas?

  45. Compounds • Atoms are joined by chemical bonds to form compounds • A chemical formulagives the types and relative numbers of atoms in a substance

  46. Chemical Formulae • Simplest formula • smallest whole-number ratio of component atoms • Molecular formula • actual numbers of each type of atom • Structural formula • the arrangement of atoms in a molecule

  47. KEY CONCEPTS • A molecule consists of atoms joined by covalent bonds • Other important chemical bonds include ionic bonds and hydrogen bonds

  48. Learning Objective 6 • Why is the mole concept so useful to chemists?

  49. Avogadro’s Number • Avogadro’s number 6.02 x 1023 • One mole (atomic or molecular mass in grams) of any substance contains 6.02 x 1023 atoms, molecules, or ions • Enables scientists to “count” particles by weighing a sample
