Carbon dating used for
Carbon has four empty spaces in its outer shell, enabling it to bond to four other atoms.(It can also bond stably to fewer atoms by forming double and triple bonds.) In other words, carbon has options.A 2010 paper in the journal Nano Letters reports the invention of flexible, conductive textiles dipped in a carbon nanotube "ink" that could be used to store energy, perhaps paving the way for wearable batteries, solar cells and other electronics.Perhaps one of the hottest areas in carbon research today, however, involves the "miracle material" graphene. It's the strongest material known while still being ultralight and flexible. Mass-producing graphene is a challenge, though researchers in April 2014 reported that they could make large amounts using nothing but a kitchen blender.Carbon has two electron shells, with the first holding two electrons and the second holding four out of a possible eight spaces.When atoms bond, they share electrons in their outermost shell.
In 1985, Rick Smalley and Robert Curl of Rice University in Texas and their colleagues discovered a new form of carbon.
Plants take it up in respiration, in which they convert sugars made during photosynthesis back into energy that they use to grow and maintain other processes, according to Colorado State University.
Animals incorporate carbon-14 into their bodies by eating plants or other plant-eating animals.
And it uses them: Nearly 10 million carbon compounds have been discovered, and scientists estimate that carbon is the keystone for 95 percent of known compounds, according to the website Chemistry Explained.
Carbon's incredible ability to bond with many other elements is a major reason that it is crucial to almost all life. The element was known to prehistoric humans in the form of charcoal.

[See Periodic Table of the Elements] Carbon occurs naturally as carbon-12, which makes up almost 99 percent of the carbon in the universe; carbon-13, which makes up about 1 percent; and carbon-14, which makes up a minuscule amount of overall carbon but is very important in dating organic objects.
