4. REVIEW OF LAST CLASS February 3rd

5. Summary: Periods 1,4,5,6 We had a standard opening. We then went to the computer lab and worked on our Atomic Super Heroes project. Period 2: We had a standard opening but due to the excessively poor class behavior, did not go to the computer lab. We took notes on elements.

6. Answer the last class’s EQ which was: Essential Question: Develop your super hero using facts from the web.

7. Topic/Objective: Name: Isotopes Class/Period: Date: Feb 4, 2015 Essential Question: Explain the differences between isotopes of the same element.

8. Warm Up

10. 2. A diagram of the periodic table of the elements is shown below. In which region of the table would nonmetals be found? A) 1 B) 2 C) 3 D) 4 1 2 3 4

11. 3. As a sample of water turns to ice, A) new molecules are formed. B) the mass of the sample is increased. C) the arrangement of the molecules changes. D) energy is absorbed by the molecules

12. 4. The following equations represent chemical reactions. Which equation shows that the total mass during a chemical reaction stays the same? A) 1B) 2C) 3D) 4 12Na + 2H 2 O 2 H 2 + O 2 3 4 NaOH + H 2 H20H20 Mg + Cl 2 MgCl 2 NAOH +MgCl 2 NaCl + MgOH

25. Tuesday January 25 121 9Standard: 7 Periodic Table Periodic Table II. Groups have similar properties. Group 1: Alkali Metals-Most reactive metals and the least dense metals –Floats on water Group 2: Alkaline Earth Metals-very reactive also but not as much as group 1 Group 3-12: Transition metals-very dense

26. Standard: 7 Periodic Table Periodic Table Group 17 Halogens –very reactive non metals. Group 18- Noble gases (inert gases)- unreactive nonmetals

27. Standard: 7 Periodic Table Periodic Table I.Similar Properties Periods –Elements across the table. (left to right) Groups or Families – Elements in a column (top to bottom)

28. Standard: 7b Isotope questions P 1 N 0 P 1 N 1 H-1 and H-2 have the same number of protons and electrons, but have a different number of neutrons. P 3 N 4 P 3 N 5 P 3 N 4 Mass number for Li-7 is 7. Mass number for Li-8 is 8.

30. Group Activity- Making large models of atoms You are working in a group to place the correct color and number of sticky notes on the large butcher paper as each atom is presented to you by your teacher. Work quickly in your group and all group members raise your hand if you have it correct. You will receive points if you have it done correctly and quickly. Example: Lithium Li-7 (Isotope) Protons-blue sticky notes Neutrons- green sticky notes Electrons-pink sticky notes 1 st energy level 2 nd energy level
