  1. The Chemistry of Life Chapter 6

  2. Basics of Chemistry • The cell is a complex chemicalfactory. • It is made of atoms, elements, compounds, and molecules.

  3. Do Now! Answer questions 1-2 on page 85 in UPCO.

  4. The Atom • Living and non-living things are made up of atoms. • The center core of the atom is the nucleus. • The nucleus is made up of particles called protons (+ charge), and neutrons (neutral charge). • Electrons (- charged) revolve around the nucleus. • Electrons move in different levels called shells, or orbits. • # electrons = # protons.

  5. Do Now! Answer questions 1-4 on pages 85, 86 in UPCO.

  6. Elements • An element is a substance made up of only onekindofatom. • There are over 110 elements (92 occur naturally- the others are man made). • Elements can’tbe broken down. • Each element is represented by a symbol (one/ or two letters).

  7. Do Now! Answer questions 1-5 on page 86 in UPCO.

  8. Compounds • Compounds are formed when two or more elements arechemically combined. • Elements combine to form compounds by a process called chemical bonding. • Bonds occur by the sharing (covalent) or transferring(ionic) of electrons between atoms.

  9. Do Now! Answer questions 1-3 on page 87 in UPCO.

  10. Molecules • It is the smallestpart of an element or compound. • It is capable of independentmotion. • It is made up of definite numbers and kinds of atoms bonded together.

  11. Do Now! Answer questions 1+2 on page 88 in UPCO.

  12. Ions • An ion is an atom that has lost or gainedelectrons. • The atom has become electronicallycharged. • Chemical bonds formed by losing or gaining electrons are called ionicbonds.

  13. Do Now! Answer questions 1+2 in the middle of page 88 in UPCO.

  14. Covalent Bonds • These bonds are formed when electrons are shared.

  15. Do Now! Answer question #1 at the top of page 89 in UPCO.

  16. Chemical Formulas • A chemical formula represents the chemicalmakeup of a compound. • It shows the kinds, numbers, and arrangements of atoms (structural formula).

  17. Do Now! Answer questions 1-5 on page 89 in UPCO.

  18. Equations • Equations are used to describe chemicalreactions. • The substances that start the reaction are called the reactants (left side of equation). • The substances made by the reaction are called the products (right side of the equation).

  19. Do Now! • Answer questions 1-5 on page 90 in UPCO.

  20. Organic and Inorganic Compounds • Inorganic compounds do not contain hydrogen and carbon. • Organic compounds do contain both carbon and hydrogen.

  21. Do Now! Answer questions 1-3 on the bottom of page 90 in UPCO.
