3 Learning Targets: 1 Below Standard 2 Approaching Standard 3 At Standard 4 Above Standard A: I can describe the relative charges, masses, What are the relative charges of protons, neutrons, and What are the relative masses of protons, neutrons, and Draw a picture of an atom, labeling where electrons, Describe how electrons move around the nucleus of an atom. and locations of the protons, neutrons, and electrons in an atom. electrons? electrons? What units are used for these masses? neutrons, and protons are found. Activities/Evidence: B: I can explain what happens to an atom when you change the number of protons, neutrons, and electrons. Activities/Evidence: If a neutral atom has 5 protons, how many electrons will it have? How are atomic number, mass number, and atomic mass different? What is the atomic number of Carbon? What is the mass number of carbon if it has 7 neutrons? Using the atomic mass, what is the most common isotope of Oxygen? How many neutrons and protons are present in this isotope? 2

4 C: I can identify the mass number, number of protons, number of neutrons, and identity of an atom using the periodic table. Activities/Evidence: Element # Protons Fill out the following table. Fill out the following table. Fill out the following table When do isotopes become unstable? Is it the same throughout the whole periodic table? Copper (Cu) Gold (Au) Barium (Ba) 19 3 Mass # # p + #n Element # p + #n 0 C-13 F-18 Ta-182 H-2 D: I can predict the chemical properties of an element based on its valence electrons. Activities/Evidence: How many valence electrons do most atoms want? Which of the following atoms have the same number of valence electrons: calcium, sodium, fluorine, chlorine, sulfur. How does reactivity change as you move across the periodic table? Why are alkali metals so reactive? Which is the most reactive? E: I can explain the arrangement of the periodic table, including significant relationship among elements in a given column or row. Activities/Evidence: Elements in the periodic table are arranged based on increasing. What are the columns called? Rows? What do each of the periods in a periodic table represent? What subatomic particle do they correspond to? How does atomic radii change across a period? How does reactivity change down a group? Why are halogens so reactive? Why are noble gases inert? (Be sure to mention electrons) 3

5 Scientific Contributions Cartoon Hmmm I wonder if I could keep cutting this in half forever?... Probably not, before long it would be too small to see. It would become invisible. Ah Ha! Invisible, indivisible The Atom Scientists and their contributions: Date: Scientist: 2 important contributions to the Atomic Theory: Date: Scientist: An Atom must be much like a miniature solar system with electons in orbit about the nucleus, much like our planets orbit our sun. 3 important contributions to the Atomic Theory: Date: Scientist: 2 important contributions to the Atomic Theory: To my great astonishment I have discovered that the atom is mostly empty space. It seems to be occupied by a small dense positive force surrounded by negatively charged particles. And so all elements are made of atoms. 1. Atoms are invisible, indivisible particles 2. Atoms of the same element are identical 3. Atoms of different elements are dissimilar 4. When two or more elements chemically combine they form a compound Date: Scientist: 4 important contributions to the Atomic Theory: These are the critical parts of MY Atomic Theory! Date: Scientist: My research has led me to believe that there are both positive and negative forces at work within the atom. 2 important contributions to the Atomic Theory: 4
