Answer :

Final answer:

The periodic table is used to identify elements and classify them as metals, nonmetals, metalloids, or noble gases. Examples of these classifications include lithium as a metal, oxygen as a nonmetal, germanium as a metalloid, and selenium as a nonmetal.

Explanation:

To identify the names and classifications of elements based on their symbols, we can refer to the periodic table. Metal elements are generally found on the left side of the periodic table, while nonmetals are usually on the right side. Metalloids, also known as semi-metals, are located along the border between metals and nonmetals. Noble gases are a specific group of elements found in Group 8A of the periodic table. Here are a few examples:




  3. Lithium (Li) - metal

  6. Oxygen (O) - nonmetal

  9. Germanium (Ge) - metalloid

  12. Selenium (Se) - nonmetal
