carbon
Let an agent explain carbon as an element, its allotropes, isotopes and chemistry, describe the carbon cycle and its role in climate, describe uses in materials and industry, and support learning.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain carbon as an element, its allotropes, isotopes and chemistry, describe the carbon cycle and its role in climate, describe uses in materials and industry, and support learning.
The chemical element with atomic number six, a nonmetal that forms more compounds than any other element and is the basis of organic chemistry and life, occurring as allotropes including diamond, graphite, graphene, fullerenes, nanotubes and amorphous forms such as hard carbon, with isotopes including stable carbon-12 and carbon-13 and radioactive carbon-11 and carbon-14; carbon cycles through the atmosphere, oceans, rocks and living things, and its compounds are central to fuels, materials and climate.
What it is for: Element six, basis of organic chemistry.
It can be explain the element and allotropes; describe the carbon cycle; describe uses; support learning.
Distinguishing features
Four valence electrons
Allotropy
Basis of organic chemistry
Biogeochemical cycling
What it looks like
Black graphite, transparent diamond, or amorphous soot and charcoal.
How it is recognised
Atomic number six
Diamond, graphite and other allotropes
Carbon dioxide is a compound; carbon as a fuel means coal or charcoal
