Section+3+(Chapter+1)+Summary

This section talks about elements and the types of elements there are. Each element in the periodic table has its own unique symbol. The properties of each element vary across the rows, or periods of the Periodic Table. The elements are split up into groups called metals, nonmetals, metalloids, and noble gases. Metals are very shiny elements, and tend to be good conductors. Nonmetals are very brittle, and are poor conductors. Metalloids are in the middle of having properties between metals and nonmetals. They are usually semiconductors of electricity. As for the noble gases, they are generally unreactive.
