3. Bell Work Answer

4. Word Wall Words- Quiz Friday! Add these in the back of your SNB in the vocabulary section. 11. Mixture- combination of two or more substances that are not chemically combined. 12. Solution- a homogeneous mixture of two or more substances uniformly dispersed throughout a single phase. 13. Solute- in a solution, the substance that dissolves in the solvent 14. Solvent- in a solution, the substance in which the solute dissolves. 15. Suspension- a mixture in which particles of a material are more or less evenly dispersed throughout a liquid or gas.

5. EQ: Do I recognize that all matter consists of atoms? (SPI0807.9.1) TOC: #45. Atom’s Family #46. Atoms Foldable #47. Candy Atoms Student Learning Objectives:

6. 45. Atom’s Family 1st Verse: They’re tiny and they’re teeny, Much smaller than a beany, They never can be seeny, The Atoms Family. Chorus 2nd Verse: Together they make gases, And liquids like molasses, And all the solid masses, The Atoms Family Chorus 3rd Verse: Neutrons can be found, Where protons hang around; Electrons they surround The Atoms Family. Chorus Chorus: They are so small. (Snap, snap) They’re round like a ball. (Snap, snap) They make up the air. They’re everywhere. Can’t see them at all. (Snap, snap)

7. 46. Atoms Foldable- outside Neutrons Protons Electrons Atoms

8. Atoms Foldable- Inside Atoms- The smallest unit that an element can be divided intoand still be the same substance. the same number of protons Isotopes- the same number of protons but have different numbers of neutrons. (Isotopes are the same as the Mass #) Atomic Mass= #Protons + #NeutronsAtomic Number= # Protons#Protons= #Electrons Neutrons- Neutral particle NO charge (0) Inside the nucleus ½ of atom’s mass Keeps protons together Neutrons= Atomic mass- Atomic # Protons- Positively Charged (+) Inside the nucleus The other ½ of atom’s mass #Protons= Atomic # (Element’s Identity) Electrons- Negatively Charged (-) Outside the nucleus in the electron cloud No effect on atom’s overall atomic mass. Responsible for ability to form bonds.

9. Student Demo Protons (+) Neutrons (0) Electrons (-)

10. Make a connection! How Do Atoms of Different Elements Differ? Discuss with your elbow partner!

11. Element Connection! For example: The hydrogen atom has 1 proton and 1 electron. The hydrogen atom has 1 proton and 1 electron. The helium atom has 2 protons, 2 neutrons, and 2 electrons.The helium atom has 2 protons, 2 neutrons, and 2 electrons. For bigger atoms, simply add protons, neutrons, and electrons.For bigger atoms, simply add protons, neutrons, and electrons.

12. Atoms Example: Boron Atom Atomic Mass – 11 Atomic Number – 5 # of Protons - 5 # of neutrons - 6 # of electrons - 5 Bohr Model Key: Proton Neutron Electron

13. 47. Candy Atoms- Skittles Materials: Skittles: red, yellow, and orange Coffee filter Periodic Table SNB Your task: 1. Use the Periodic Table to arrange the Skittles on your coffee filter for the number of protons, neutrons, and electrons. 2. Use the BLUE cup to show that your group is finished and let me check. 3. Once your group has been checked, draw each in your SNB. 4. DO NOT EAT the candy until directed by me! KEY: Red – Protons Yellow – Neutrons Orange – Electrons Elements: Hydrogen Carbon Helium Nitrogen Lithium Neon

14. Exit Ticket 1.What are atoms? Where are they found? 2.Compare and contrast protons, neutrons, and electrons. Give examples.

15. Practice with Protons, Neutrons, Electrons, Mass #, Atomic # Directions: At your groups, you have a large Bohr Model. You will also have circles to represent protons(+), neutrons(0), and electrons(-). Your group will use the information given about certain elements and show a model of each element. 1.Use the Element cards at your group and show the number of electrons, neutrons, and electrons for each element. 2. Use circles to represent the particles in the atom. (Use 3 different colors to represent the atom particles) Protons Neutrons Electrons Nucleus Electron Cloud Nucleus
