Metals, Nonmetals and Metalloids Study Guide 1. The table of characteristics for samples of four different materials is provided. Which sample is most likely classified as a metal? 2. The diagram shows the location of some elements on the Periodic Table. Circle the element that is classified as a metalloid? Lead (Pb) Beryllium (Be) Silicon (Si) Fluorine (F) 3. Why are electrical wires made from metals such as copper and chromium? ____________________ _________________________________________________________________________________________ 4. A portion of the Periodic Table is shown. Which element would be expected to have a reactivity similar to phosphorous? 5. What properties are used to classify elements as metals, nonmetals, or metalloids? ________________________________________________________________________________ 6. The table shows the properties of three classifications of elements. What are the best headings for columns A, B, and C? 7. Some students conducted a laboratory investigation to learn more about the physical properties of different elements. They observed four samples and recorded their observations in the table below. Based on these observations, label the samples as metal, nonmetal, or metalloid. 8. The table shows the classification and physical state of four elements.
