Shown (red dots) is a large number of identical atomic nuclei, each obeying the same decay law.
Coal is also a key component in steel production, while graphite, another form of carbon, is a common industrial lubricant. Arrange carbon atoms in one way, and they become soft, pliable graphite. — the atoms form diamond, one of the hardest materials in the world.Carbon is also the key ingredient for most life on Earth; the pigment that made the first tattoos; and the basis for technological marvels such as graphene, which is a material stronger than steel and more flexible than rubber.Carbon-14 is a radioactive isotope of carbon used by archaeologists to date objects and remains.Carbon-14 is naturally occurring in the atmosphere.
[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.
