1. The Periodic Table Catalyst Take out your periodic table to answer the following questions: 1. What are the periods and groups on the periodic table? Periods are the horizontal rows and groups are the vertical columns. 2. How do you find the number of neutrons in an atom? How many neutrons are in boron? Atomic mass – atomic number = number of neutrons. 11 – 5 = 6, there are 6 neutrons in boron 3. Draw a Bohr model (electron rings and nucleus) for carbon. 29L 11/14/11

2. The Periodic Table Learning Target #4 (Reminder) LT #4: I can read and understand the periodic table of elements and explain all the different sections. New bathroom policy: 1 until winter break. Nonverbal, just raise 2 fingers. 11/14/11 29R

3. VI. Families and periods A. The number of rings and number of electrons on the last ring of any given element determines it position on the period table. B. Groups- vertical columns *Similar chemical properties 29R 11/14/11

4. C. Each horizontal row on the periodic table is called a period. *Not alike, but have the same number of energy levels http://www.brainpop.com/science/matterandchemi stry/isotopes/ 29R 11/14/11

5. Isotopes = Atoms of the same element that have different numbers of neutrons Example: Carbon-12, Carbon-13, and Carbon-14 Think-Write-Pair-Share 1. How many neutrons does each one have? How many protons and electrons? 2. What about for hydrogen? There is hydrogen-1, hydrogen-2, and hydrogen-3. 29R 11/14/11

6. The Periodic Table Stations Practice You have 10 minutes at each station to complete the worksheet in your notebook. Do NOT write on the worksheets!! 29L 11/14/11

7. The Periodic Table Catalyst 1. What is an isotope? Atoms of the same element that have different numbers of neutrons 2. Find the # of protons, neutrons, and electrons in Cl-35 and Cl-37. 29L continued 11/16/11

9. The Periodic Table 29R 11/16/11 Metals are elements that are good conductors of electric current and heat. They are also shiny and bendable. The majority of elements in the periodic table are metals. Physical Properties Luster (shininess), malleability (can be hammered into flat sheets), ductility (can be rolled into long wire), and conductivity (thermal, transfer heat, and electrical, transfer electric current) Chemical Properties Reactivity – the ease and speed with which a substance reacts with other substances, Na reactive and Au unreactive Corrosion – the gradual wearing away of a metal due to a chemical reaction, rust Alkali MetalsDefinition, examples and location on periodic table Alkaline Earth MetalsDefinition, examples and location on periodic table Transition MetalsDefinition, examples and location on periodic table 29R continued
