2. Draw a wave and label the crest, trough, and wavelength.

3. Draw a picture of the different types of electromagnetic radiation and show the high energy             low energy and long wavelength            short wavelength. Make sure to label all the different types of energy.

4. Explain what happens when an electron in an atom becomes excited.

5. When an electron is excited a photon is ____________. When an electron returns to ground state a photon is _____________.

10. Show how atomic size changes across and down the atomic period. Draw in how the size of the atom changes and draw arrows showing how it changes.

11. Metals tend __________ electrons. Nonmetals tend to __________ electrons.

12. Show how the ionization energy changes as you move across the period and down the groups of the periodic table.  Draw the table and label with arrows and words to show the changes of ionization energy of the periodic table.
