  1. DEFINE PHYSICAL PROPERTIES AND LIST AT LEAST 3 EXAMPLES P. 94

  2. An observable property of matter that can be determined without changing the substance.Ex: color, density, luster, odor, BP, MP

  3. HOW IS A PHYSICAL CHANGE DIFFERENT FROM A CHEMICAL CHANGE? P. 94

  4. In a physical change, the substance remains chemically identical. In a chemical change, a new substance is formed.

  5. DEFINE CHEMICAL PROPERTIES. P. 94

  6. Properties that require a change in the chemical makeup to observe.Ex: flammability

  7. __________ __________, A RUSSIAN CHEMIST PUBLISHED THE FIRST PERIODIC TABLE IN 1869. P. 100

  8. Dimitry Mendeleev

  9. DEFINE PHYSICAL CHANGES AND LIST AT LEAST 3 EXAMPLES. P. 94

  10. A change results in the same substance in the end.Ex: ripping paper, changing states of matter

  11. IN THE MODERN PERIODIC TABLE, ELEMENTS ARE PLACED IN SEQUENCE ACCORDING TO ______________________. P. 102

  12. Increasing atomic number

  13. DEFINE CHEMICAL CHANGES AND LIST AT LEAST 3 EXAMPLES. P. 94

  14. Changes that result in the formation of a new substance with different propertiesex: burning a piece of paper, frying an egg, food spoiling

  15. DEFINE PERIODS P. 103

  16. The horizontal rows in the periodic table. Properties are NOT similar in periods.

  17. DEFINE A GROUP (FAMILY) OF ELEMENTS. P. 105

  18. Family or group: • Same number of electrons in outer (valence) shell • Similar chemical properties Period: Same number of energy levels

  19. IDENTIFY THE ATOMIC NUMBER AND THE AVERAGE ATOMIC MASS OF THE ELEMENT BELOW P. 104 7 N 14.01

  20. Atomic # is 7 Atomic Mass is 14.01

  21. STUDY YOUR PERIODIC TABLE – KNOW THE LOCATION OF THE METALS, NON METAL AND METALLOIDS KNOW THE CHARGES ON THE ELEMENTS IN GROUPS 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A (NOTES)

  22. +1 +2 +3 +/-4 -3 -2 -1 0

  24. DESCRIBE THE PROPERTIES OF A METAL (NOTES)

  25. Properties of Metals • Shiny 'metallic' appearance • Solids at room temperature (except mercury) • High melting points • High densities • Malleable • Ductile • Thermal conductors • Electrical conductors • Electron losers

  26. What are the rules for correctly writing a chemical symbol.

  27. All have capital letters, some have a capital and a lowercase letter

  28. Describe the properties of a non metal.

  29. Propeties of Nonmetals • Poor thermal conductors • Poor electrical conductors • Brittle solids • Little or no metallic luster • Gain electrons easily • Most are gases at room temperature • Vary in color

  30. Using your periodic table, predict the formula for the compound formed from C and F d. Al and S Ca and Br e. Fe+2 and O K and CL f. Fe+3 and O

  31. CF4CaBr2KClAl2S3FeOFe2O3

  32. Describe the properties of a metalloid.

  33. They have some properties of metals, some properties of nonmetals

  34. What is the name of a compound formed when A. Fe+2 combines with OB. Fe+3 combines with O P 35

  35. Iron(II)Oxide Iron(III)Oxide

  36. Cation Anion Formula Mg+2 OH – NH+4 NO 3 - Ca+2 PO4-3

  37. Cation Anion Formula Mg+2 OH – Mg(OH)2 NH4+1 NO31 - NH4NO3 Ca+2 PO4-3 Ca3(PO4)2

  38. How does a balanced equation reflect the Law of Conservation of Matter?

  39. The number of individual atoms of elements on the reactant side must equal the number of atoms in the product sideMatter can’t be created or destroyed

  40. Name the seven diatomic elements and correctly write their symbols.

  41. H2, N2, O2, F2, Cl2, Br2, I2

  42. 2 H2O ___________^ ____________label the subscript and the coefficient.
