  15. Ch. 8 Review sheet- answers

  16. What is a chemical bond? (3 pts) • A force that holds2 or more atoms together.

  17. Why do ions form? (2 pts) • They lose or gain electrons to have a stable electron arrangement.

  18. What family of elements is relatively unreactive and why? (2 pts) • Noble Gases are unreactive because they have a filled valence orbit.

  19. Describe the formation of cation. (2 pts) • Atoms lose their valence electrons becoming a positive charge.

  20. Describe the formation of anion. (2 pts) • Atoms gain electrons becoming a negative charge.

  21. Explain the formation of the ionic compound composed of lithium and oxygen. (4pts) • Oxygen gains both of those electrons becoming a -2 charge. • 2 Lithium atoms loses their valence electron becoming +1 charge. • They fill create a stable orbital arrangement • Cancel each other charges out.

  22. Provide the 5 properties of an Ionic substance. (5 pts) • High melting point • Dissolves in water • Conductive (after being dissolved in H2O) • Solids at room temperature • Brittle (not malleable)

  23. What is lattice energy? (3pts) • Energy needed to separateions from its compound.

  24. Which compound would have more lattice energy- NaCl and AlCl3? Explain your reasoning. (2 pts) • AlCl3 would need more energy because it has 3 electrons being transferred which would need more energy to pull them apart.

  25. What is the difference between a formula unit, and crystal lattice (3 pts) • Formula Unit is the simplest form of an ionic compound- NaCl. • Crystal Lattice is the repeating formula unit forming a lattice. NaClNaClNaClNaCl NaClNaClNaCl NaClNaClNaClNaCl NaClNaClNaCl

  26. Define oxidation number. (1pt) • The charge on an ion.

  27. What is the difference between a monatomic ion and a polyatomic ion? (4 pts) • Monatomic ion is a one atom ion. • Polyatomic ion is a 2 or more atoms that are covalently bonded that carry a charge.

  28. For the following formula, provide the correct names (5 pts) Fe2(SO3)3________________(H3O)3BO3________________Hg3(PO4)2________________Cu2CO3________________Al(NO3)3________________ Iron III sulfite Hydronium borate Mercury II phosphate Copper I carbonate Aluminum nitrate

  29. For the following names, provide the formula (5 pts)Gallium cyanide _________________Bismuth III chromate ______________Iron III hydroxide _________________Hydronium phosphide______________Copper I selenate_________________ Ga(CN)3 Bi2(CrO4)3 Fe(OH)3 (H3O)3P Cu2SeO4

  30. Flip paper overTo Know ListSTUDY for P of UCh. 2-8

  31. To Know List- Ch. 8 Test • Concentration of MOSTLY Ch. 8 (75%) • Why bond? • Ionic substances- properties • Naming ionic substances • Providing the formula • Transitional metals- ROMAN NUMERALS • Metallic bonds- properties • Alloys- maybe 3 questions on it

  32. To Know List- Ch. 8 Test • Concentration of MOSTLY Ch. 8 (75%) • Periodic trends- • Ionization energy • Electronegativity • Size of atoms verse ions • Energy levels-light, E-dot/valence-Ch. 5 • Particles- Protons, Electrons Neutrons-Ch. 4 • Physical chemical properties/changes-Ch. 3 • Scientific notation and Significant Figs- Ch. 2 25%
