The Wonder Element

“No element is more essential to life than carbon,” says the book Nature’s Building Blocks. The unique characteristics of carbon enable it to bond with itself and many other chemical elements, thus forming millions of compounds, more of which are constantly being discovered or synthesized.
As the examples here show, carbon atoms can also combine to form various shapes, including chains, pyramids, rings, sheets, and tubes. Carbon truly is a wonder element!
DIAMOND
Carbon atoms form pyramids, called tetrahedrons, making the structure extremely rigid and making diamond the hardest naturally occurring substance known. A perfect diamond is essentially a single molecule of carbon atoms.
GRAPHITE
Tightly bonded carbon atoms are set out in loosely bonded layers that can slide away from one another like sheets of paper on a stack. Because of these characteristics, graphite is both a fine lubricant and a key compound in lead pencils.
GRAPHENE
This refers to a single layer of carbon atoms arranged in a hexagonal mesh, or lattice. Graphene has a tensile strength many times that of steel. A pencil trace may have small amounts of graphene in single or multiple layers.
FULLERENES

These hollow molecules of carbon come in shapes that include microscopic balls and tubes called nanotubes. They are measured in nanometers, or billionths of a meter.
LIVING ORGANISMS
The many cells that make up plants, animals, and humans are built on a framework of carbon—an element found in carbohydrates, fats, and amino acids.

Carbon—A Product of Ultrafine Tuning in the Stars

Carbon is formed by the fusion of three helium nuclei, which scientists believe occurs inside stars called red giants. For the helium to combine, however, certain conditions must be exactly right. “Change just a few of the settings [of physical laws] even an infinitesimal amount,” wrote physicist Paul Davies, and “we’d have no universe, no life and certainly no humans.” How can we account for such ultrafine tuning? Some say it just happened. Others see it as evidence of a wise Creator. Which view do you consider more reasonable?
