Do Now: • Before the BELL RINGS, turn your Element Foldable into the basket in the back of the room • Complete Welcome Work: • Do #’s 1-10 of the worksheet “Elements” in your Science Notebook • This will be page number 22 • Study Chapter 12 if you finish early
Student Objectives: Locating metals, nonmetals, and noble gases on the periodic table Using data about the number of electrons in the outer shell of an atom determine its reactivity Describe the properties of the elements in the groups of the periodic table. Chapter 12 Review Day
Answers to “Elements” worksheet • Gold • 1. Shiny • 2. Can be hammered into sheets • 3. Conducts heat and Electricity • 4. can be pulled into wires
Helium • 5. non-conducting • 6. lighter than air (less dense than air) • 7. occurs naturally as a gas
Mercury • 8. Poisonous • 9. Occurs naturally as a liquid • 10. Shiny
Halogens • The word halogen comes from the Greek words meaning “salt former.” • Sodium Chloride, or table salt, is composed of the halogen chlorine and the alkali metal sodium.
Plant Fertilizers • Chemical fertilizers and organic fertilizers show their nutrient content with three bold numbers on the package. These numbers represent three different compounds: Nitrogen, Phosphorous, and Potash (Potassium), which we can also describe with the letters N-P-K. The three numbers listed on fertilizer labels correspond to the percentage of these materials found in the fertilizer.What does each nutrient do? In addition to other properties, Nitrogen helps plant foliage to grow strong. Phosphorous helps roots and flowers grow and develop. Potassium (Potash) is important for overall plant health
Periodic Table Lab • You will need your Science notebook and a pencil • You may not look up the answers to the questions using your SNB • There will be no running • You must remain standing during this lab. • There will be no talking • If you have a question raise your hand.
