  1. In your notebook describe how you know when you have learned something. Now explain solubility and density. Warm-up

  2. List how many protons and electrons the following elements have: Hydrogen, Sodium, Iron, Krypton, and Mercury Warm-up

  3. Create a master piece about what you have learned about matter using words and paint Painting atoms

  4. Draw the atomic structure of an element from the periodic table. Label the nucleus, protons, neutrons, electrons and charges. Warm-up

  5. Create a rap, song, poem, or paragraph. Explain how the atoms in the following objects would change when heated and cooled. CHOOSE AT LEAST 3 OBJECTS Peach ice cream Soda uncooked hot dog soda can chocolate candy bar Rap Song homework

  6. Construct an analogy: Atom:Element as ________: _________ Warm-up

  7. The Atom and the periodic table

  8. Describe and define atoms. • Name the parts of an atom. • Describe the relationship between numbers of protons and atomic number on the periodic table. Objectives

  9. How is matter alike or different on the molecular level? How is the # of Protons related to the atomic # on the periodic table? ESSENTIAL QUESTIONs

  10. What is a pure substance? Is a substance in which there is a uniform composition of “particles”. The particles we are talking about are atoms.

  11. What is an element? meet the elements song A substance that Contains only one type of atom. All known elements are organized on the periodic table of elements. atoms and elements

  12. What is a compound? Is a combination of elements that come together through a chemical reaction and becomes something called a molecule. • A molecule is two or more different elements combined in a specific ratio.

  13. What is an atom? The smallest part of an element that has the same properties of that element. In Greek means-“Uncuttable” atom animation

  14. Atom cont… • These particles are too small to be seen with a microscope. • Atoms have all the properties of matter: mass and volume • What is an atom?

  15. Superman Study Jams atoms

  16. What Is • an atom • Made • of? Protons – Found in the atom’s nucleus and has a positive charge. Protons +

  17. What Is • an atom • Made • of? Neutrons – Found in the atom’s nucleus and has no charge. The nucleus contains most of the atom’s mass n What 2 things are found inside the nucleus? Neutrons Neutrons Protons

  18. - • What Is • an atom • Made • of? Electrons – Found circling the atom’s nucleus. - Each has a negative charge. Electron

  19. Label Me! 1. 3. 2. 4.

  20. The atomic number is the number of Protons in the nucleus of that atom. All atoms of an element have the same atomic number. What is the atomic number?

  21. Here is an example of one of the elements on the periodic table. atomic number - # of protons in the nucleus. 3 Li Lithium 6.94 element symbol element name atomic mass –mass of the protons and neutrons

  22. What is the Atomic Number?

  23. Atom Atomic mass Isotopes

  24. How do Atoms of Different Elements Differ? • Starting Simply The hydrogen atom has one proton and one electron. • Now for Some Neutrons The helium atom has two protons, two neutrons, and two electrons. • Building Bigger Atoms For bigger atoms, simply add protons, neutrons, and electrons. • Protons and Atomic Number . The atomic number represents the number of protons in the nucleus of the atom.

  25. Vocabulary you should be familiar with so far… Matter Volume Mass Density Solubility Solute Solvent Physical Changes Atom Elements

  26. Describe and define atoms. • Name the parts of an atom. • Describe the relationship between numbers of protons and atomic number on the periodic table. Objectives review

  27. How is matter alike or different on the molecular level? How is the # of Protons related to the atomic # on the periodic table? ESSENTIAL QUESTIONs
