Group 14, the Carbon Group & Group 13, the Boron Family

Carbon: Carbon (a nonmetal) exists in several different common forms. Just by thinking you should know the 2 most common: diamond and graphite.

Boron: The elements in the Boron family are not all solid metals. a single group can contain metals, nonmetals, and metalloids. All of which can have members that are solids, liquids, and gases.

Group-14: Carbon Carbon is found in all living things. Carbon is followed by the metalloid silicon, an abundant element, found in sand. Sand contains ground up particles of minerals such as quartz, which is composed of silicon and oxygen.

Group-14: Carbon Group 14 and its neighbor, germanium, are all metalloids. They are used in electronics as semiconductors. A semiconductor doesn’t conduct electricity as well as metal, but does conduct electricity better than a nonmetal.

Group-14: Carbon Tin and lead are the two heaviest elements in Group 14. Lead is used to protect your torso during X-rays. It also is used in car batteries, low-milting alloys, protective shielding around nuclear reactors, and containers used for storing and transporting radioactive materials. Tin is used in pewter, toothpaste, and the coating on steel cans used for food.

Group-13: Boron The elements in Group 13 are all metals except boron, which is a brittle, black metalloid. Boron is extremely temperature resistant though. Cookware made with boron be moved directly from the freezer into the oven without cracking.

Group-13: Boron Aluminum, part of the boron family is used to make soft-drink cans, cookware, siding for homes, baseball bats, and all matter of various products. Gallium is a solid metal, but its melting point is so low that it will melt in your hand.
