carbon
Organic chemistry's backbone
Carbon is a chemical element fundamental to life on Earth—the backbone of organic chemistry.
All known living things are carbon-based.
Carbon atoms bond readily with other elements, forming millions of compounds.
Pure carbon appears as diamond, graphite, and other forms.
A carbon footprint measures greenhouse gas emissions.
Carbon dating determines the age of organic materials.
