3 Part 3 Periodic Table (continued) SE, p. 504 RE, p. 293 Review how electron dot diagrams show similarities between elements in a group. Accept all reasonable answers. Elements within a group have the same electron dot diagram because they have the same number of electrons in their outermost energy level. They are both in section SE of the periodic table, p. 505 RE, p. 294 How to connect them with other elements to complete the outer level. Classify the periods in the periodic table as metals, nonmetals, or metals. Shade the region in the empty periodic table. Label each region and write its characteristics. Write this Write a paragraph that shows the relationship between chemistry and physics based on what you have learned about the periodic table. Accept all reasonable answers. Students can say that both electrical and magnetic chemical reactions can be described in terms of energy and force. The structure of an atom is defined in terms of energy. The reactivity between atoms is expressed in terms of energy. 200 properties of atoms and periodic table

4 Connect Properties of Atoms and the Periodic Table to Scientists Because arranging the elements on the periodic table is good for scientists, create your own tables to organize other classes of elements. Select a set of items that show repeated and predictable patterns of behavior. List the attributes in their order and arrangement and arrange them in rows and columns. Review your organizational strategy. Some suggestions include fashion or fashion trends, music genres, drinks or political trends and elections. Accept all reasonable answers.
