  1. Station 1 An ionic bond is between what types of elements? Anything ending in –ate or –ite is most likely what? What is the formula unit for Lithium Nitride? What is the formula for Calcium Bromide? What is the name of Al2O3?

  2. Answers Station 1 • A metal (cation) and a nonmetal (anion) • A polyatomic ion • Li3N • CaBr2 • Aluminum Oxide

  3. Station 2 • What is the name of CuSO4? Honors-What is the “ous-ic” name? • What is the name of Li3PO4? • What is the name of AgF? • What is the formula for Magnesium Carbonate? • What is the formula for Copper (II) Chloride?

  4. Answers Station 2 • Copper (II) Sulfate • Lithium Phosphate • Silver (I) Fluoride • MgCO3 • CuCl2

  5. Station 3 • What are three characteristics of Ionic Compounds? • How do the group 1 elements obey the octet rule? • What is the charge on a Beryllium Ion? • What is the net charge on an ionic compound? • What is the basis of a metallic bond?

  6. Answers Station 3 • High Melting Point, Crystalline Solids, Conduct electricity when melted or dissolved in water • They lose 1 electron • +2 • 0- neutral • The attraction of metal ions to mobile d electrons

  7. Station 4 • What is the octet rule? • What is a valence electron? • What is electronegativity? • Name the seven diatomic elements. • Why do atoms share electrons in a covalent bond?

  8. Answers Station 4 • In chemical compounds atoms tend to have the electron configuration of a noble gas • An electron in the highest energy level • The ability of an atom to attract electrons towards itself • Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, and Iodine • To achieve the electron configuration of a noble gas

  9. Station 5 • What is the formula for Carbon Tetrachloride? • What is the name of BN? • What is the formula for Sulfur Trioxide? • How are molecular orbitals formed? • Molecular Compounds are composed of what?

  10. Answers Station 5 • CCl4 • Boron Mononitride • SO3 • Atomic orbitals from two different atoms overlap • Two or more nonmetals

  11. Station 6 • Draw lewis structures and tell the number of sigma(σ) and pi(π) bonds (Honors) in each. • NCl3 • SO2 • ClO4- • CH4 • VSEPR says that molecules have certain shapes to keep what as far apart as possible? • What is the shape of the molecules in question 1?

  12. Answers Station 6 • a) σ: 3 π: 0 b) σ: 2 π: 1 c) σ: 4 π: 0 d) σ: 4 π: 0 • Valence Shell Electrons • a. Pyramidal b. Angular/bent c. Tetrahedral d. Tetrahedral

  13. Station 7 • Define a polar covalent bond and a non-polar covalent bond. • Tell whether the following are ionic, polar, or non-polar bonds. • N-N c. Na-Br • H-F d. C-O • Are the following molecules polar or non-polar? • NCl3 • SO2 • ClO4- • CH4

  14. Answers Station 7 • A polar covalent bond is a bond where electrons are not shared equally. It is between two different nonmetals. A nonpolar covalent bond is a bond where the electrons are shared equally. It is between two nonmetals that are the same element. • a. N-N: Nonpolar c. Na-Br: Ionic b. H-F: Polar d. C-O: Polar • a. NCl3 : Polar b. SO2 : Polar c. ClO4- : Nonpolar d. CH4 : Nonpolar

  15. Station 8 • Rank the intermolecular forces from weakest to strongest. • What causes dispersion forces? dipole interactions? Hydrogen bonding? • What types of intermolecular forces are found in the following molecules? • NCl3 • SO2 • ClO4- • CH4

  16. Answers Station 8 • London/Dispersion< Dipole Interactions<Hydrogen Bonding • Dispersion forces are caused by the movement of electrons causing momentary charges leading to a slight attraction between the molecules. Dipole Interactions is caused by the attraction of polar molecules for each other. Slightly positive sides are attracted to the slightly negative sides. Hydrogen Bonding is a stronger version of dipole interactions. • a. NCl3 : Dispersion, Dipole Interactions b. SO2 : Dispersion, Dipole Interactions c. ClO4- : Dispersion d. CH4 : Dispersion

  17. Station 9 • What type of solid has the highest melting point? • Give 2 examples of macromolecules • Describe how the number of bonds effects the bond energy and bond length.  Cite evidence from the chart below in your answer.

  18. Answers Station 9 • Network Solid • Ice, DNA, Polymers, Proteins, Graphite • As more bonds are added the bond energy increases. This is seen in the carbon set. A carbon-carbon single bond has a bond energy of 331kj/mol, a double bond has a bond energy of 590kj/mol, and a triple bond has a bond energy of 812kj/mol. Bond length gets shorter as more bonds are added. The carbon set shows that the length decreases from 0.154nm-0.120nm.
