Exploring Group 13: The Boron Family in Chemistry
Discover the elements in Group 13, known as the Boron Family, which includes metals like aluminum and gallium, and the metalloid boron. Learn about their properties, uses in everyday items like cookware and soft-drink cans, and unique characteristics such as gallium's low melting point. Explore how these elements differ from those in Groups 1 and 2, showcasing a variety of states (solid, liquid, gas) and chemical behaviors. Dive into the fascinating world of representative elements and their applications in technology and daily life.

Presentation Transcript
Representative Elements Groups 13 through 18 The elements in Groups 13-18 are not all solid metals like the elements of Groups 1 and 2. In fact, a single group can contain metals, nonmetals, and metalloids and have members that are solids, liquids, and gases.
Representative Elements Group 13 The Boron Family The elements in Group 13 are all metals except boron, which is a brittle, black metalloid. Cookware made with boron can be moved directly from the refrigerator into the oven without cracking.
Representative Elements Group 13 The Boron Family Aluminum is used to make soft-drink cans, cookware, siding for homes, and baseball bats. Gallium is a solid metal, but its melting point is so low that it will melt in your hand. It is used to make computer chips.
