I can …
1. Determine the atomic number of an element from the periodic table.
2. Use the periodic table to determine the electron configuration (i.e. 1s2, 2s2, 2p6, etc.) as well as the number of protons, neutrons and electrons in an atom.
3. Draw, label and describe the position of electrons in energy levels around an atom from the first three periods (rows). This will include the number and location of outermost (valence) electrons.
4. Identify the periods (rows) in a periodic table as representing the principal energy level of outer (valence) electrons.
5. Identify the groups (columns) in a periodic table as representing families (groups) of elements with similar properties because of their similar arrangement of valence electrons in energy sublevels.
6. Identify and describe the location and major properties of alkali metals, alkaline earth metals, non-metals, halogens, noble gasses, and transition metals on a periodic table.
7. Explain or draw the interaction between electromagnetic radiation such as visible light and the energy levels of electrons in an atom. (going from ground to excited state)
8. Identify or describe examples of ordinary events that represent electrons changing energy levels within atoms.
9. Recognize ionization as the removal of an electron from an atom and ionization energy as the amount of energy absorbed by the electron in order for it to be removed.
10. Analyze the position of elements on the periodic table and analyze trends in atomic radius, nuclear charge, ionization energy, electronegativity, and reactivity.
