**Gio Thompson and Christian Womack Period 3 __Car__****__bon__**

The group of carbon is 14 and the period is 2 on the periodic table. The five elements that make up the carbon group are: carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), Lead (Pb). The carbon group consists of purely solids at room temperature. __**Usage of Carbon In The World**__

0.09 percent of the earths crust is represented by Carbon. Although it is lightly used in the earth, it is one of the most essential elements for life on our planet. Almost all plants and animals are made up of a large percent of carbon. Carbon in the form of a diamond is the hardest rock on earth.

Carbon in the form of a solid is diamond which is the hardest rock on earth. Tin in it's solid form is a soft, weak metal. Lead in it's solid form is a very useful, commonly used tough metal.
 * __Physical Properties__**

Carbon can be burned as a fuel,it is a good conductor of electricity, and it melts a 3,550 degrees celcius. Lead melts at a lower tempurature than most metals, it easily forms alloys with other metals, and is a relatively poor conductor of heat and electricity. Tin melts at 230 degrees celcius, it does not tarnish when exposed to air,and is also a good conductor of heat and electricity. The name carbon comes from the Latin origin meaning charcoal. Another fun fact is that Carbon consists of several allotropes like graphite, diamond, and Bucky ball. Also another fun fact that we want you to know is that carbon is made in the interior of stars. __**2 Common Uses for Carbon and Germanium**__ Carbon is commonly used for diamonds and crystalline solids. Germanium is a grayish white rock that helos with stars.
