Science of carbon dating updating database examples java

While scientists sometimes conceptualize electrons spinning around an atom's nucleus in a defined shell, they actually fly around the nucleus at various distances; this view of the carbon atom can be seen here in two electron cloud figures (bottom), showing the electrons in a single blob (the so-called s-orbital) and in a two-lobed blob or cloud (the p-orbital). It can link to itself, forming long, resilient chains called polymers.

It can also bond with up to four other atoms because of its electron arrangement.

[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.

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 as coal is still a major source of fuel worldwide, providing about 30 percent of energy worldwide, according to the World Coal Association.

Coal is also a key component in steel production, while graphite, another form of carbon, is a common industrial lubricant.

By vaporizing graphite with lasers, the scientists created a mysterious new molecule made of pure carbon, according to the American Chemical Society.
