  13. 12. What is the correct formula for iron (III) oxide? • FeO • Fe2O3 • Fe3O2 • Fe(OH)3 Need help with naming? Watch this.

  14. 13. What is true about electrons in ionic bonds? • Electrons are shared equally • Electrons are shared unequally • Electrons are transferred from the metal to the nonmetal • Electrons are transferred from the nonmetal to the metal • Electrons move freely in in a “sea of electrons

  15. 14. What is true about electrons in nonpolar covalent bonds? • Electrons are shared equally • Electrons are shared unequally • Electrons are transferred from the metal to the nonmetal • Electrons are transferred from the nonmetal to the metal • Electrons move freely in in a “sea of electrons

  16. 15. What is true about electrons in polar covalent bonds? • Electrons are shared equally • Electrons are shared unequally • Electrons are transferred from the metal to the nonmetal • Electrons are transferred from the nonmetal to the metal • Electrons move freely in in a “sea of electrons

  17. 16. What is true about electrons in metallic bonds? • Electrons are shared equally • Electrons are shared unequally • Electrons are transferred from the metal to the nonmetal • Electrons are transferred from the nonmetal to the metal • Electrons move freely in in a “sea of electrons

  18. 17. Why is it incorrect to call NaCl a molecule? • Molecules contain more than two atoms • Molecules occur between a metal/nonmetal • Many ions of Na+ and Cl- exist in a crystal lattice • One ion of Na+ and Cl- have an ionic bond • The sodium ion forms a metallic bond with other sodium ions

  19. 17. What is the general trend of electronegativity on the periodic table? • Electronegativity decreases as you move to the left and up • Electronegativity decreases as you move to the right and down • Electronegativity decreases as you move to the left and down • Electronegativity decreases as you move to the right and up

  20. 17. Which is more electronegative, carbon, nitrogen, sulfur or phosphorus? • carbon • nitrogen • sulfur • phosphorus
