  1. Chapter 10 Atomic Structure and the Periodic Table

  2. April 14 Day 1 DRQ: Make a list of elements and symbols that you know. Activities: • DRQ\Review DRQ • Take out your Atoms packet. We will work through it together. Closure: Review the fill ins. Homework: Finish the front page of the packet.

  3. April 15 Day 2 DRQ: Read over the names and symbols on the periodic table. Write a 5 sentence paragraph. The topic - My favorite element. Activities: • DRQ\Review DRQ (check for homework completion) • Review packet. (overhead) • Video Lesson – Elements of Chemistry Closure: Quiz Homework: Complete video assessment sheets

  4. April 16 Day 3 DRQ: What is the symbol for the element with an atomic number of 36? Activities: • DRQ\Review DRQ • Bill Nye Closure:Start homework Homework: Bohr Model and Electron Cloud model of an atom

  5. April 17 Day 4 DRQ: How many protons, neutrons and electrons does an atom of Sn have? Activities: • DRQ\Review DRQ • Atoms and Elements Quiz • Hands on - Models of Atomic Structure • See pages 274 and 275 • Page 274 Table 10-3 Electrons in energy levels Closure:Clean up (save any extra electrons) Homework: None

  6. Quiz 1-5If the statement is false, correct the underlined word to make it true. • Atoms are made up of protons, neutrons and electrons. • Protons and neutrons have an electric charge. • Electrons and protons are found in the nucleus of an atom. • If you change the number of protons in the center of an atom, you change the atomic number. • The atomic number is equal to the number of protons and electrons in an atom.

  7. Quiz 6-10If the statement is false, correct the underlined word to make it true. • To find the number of electrons in an atom, subtract the protons from the atomic mass. • Chemical symbols can be one, two or three letters. • The first letter of a chemical symbol is always capitalized. • Elements at the bottom of the periodic table are heavier than elements at the top. • The electrons in an atom are attracted to the nucleus because of the neutrons.

  8. Electrons in Energy Levels • Energy level 1 • Takes 2 electrons • Energy level 2 • Takes 8 electrons • Energy Level 3 • Takes 18 electrons • Energy level 4 • Takes 32 electrons

  9. April 20 Day 5 DRQ: Lead and Mercury are two pollutants in the environment. From information about them in the periodic table, make and inference about why are they called heavy metals. Activities: • DRQ\Review DRQ (check for homework completion) • Complete Hands on - Models of Atomic Structure • See pages 274 and 275 • Page 274 Table 10-3 Electrons in energy levels • Review Homework Closure: The interactive periodic table Homework: DUE Thursday. Write a short biography of your element, include its birth date (discovery), it’s country of origin (where it was discovered), interesting facts about where it is found and why it is in the group/family on the periodic table.

  10. April 21 Day 6 DRQ: Use the periodic table to find a element whose atoms have five outer-level electrons, one with three outer electrons and one with four outer electrons. Activities: • DRQ\Review DRQ • Atoms and Elements Mini-Quiz • The Periodic table notes Closure: The interactive periodic table Homework: Write a short biography of your element, include its birth date (discovery), it’s country of origin (where it was discovered), interesting facts about where it is found and why it is in the group/family on the periodic table.

  11. April 22 Day 1 DRQ: Use the periodic table to list a metal, a metalloid and a nonmetal each with five outer-level electrons. Activities: • DRQ\Review DRQ • Groups/Cooperative learning – Our own periodic table • Using the atoms created on Friday and Monday, make a periodic table in our room on the wall. • In groups, complete any elements that are missing. Closure:Checking Concepts Questions 1-10 page 294 Homework: Using your notes from 10-1 to 10-3 and the notes from today, create a study guide about atoms, elements and the periodic table. Complete the Reviewing Vocabulary on page 293
