In this deck, we'll explore different forms of the element carbon, known as allotropes. You'll learn about the structures of diamond, graphite, graphene, and fullerenes, and see how their atomic arrangements lead to very different properties. We'll also dive into the world of nanoparticles, discovering what makes them special and looking at their uses and potential risks.

Allotropes are different structural forms of the same element in the same physical state. Diamond and graphite are both solids made only of carbon atoms, but the way those atoms are bonded together makes them behave in completely different ways.

Let's start with diamond. In a diamond, every single carbon atom is joined to four other carbon atoms by strong covalent bonds. This creates a rigid, repeating, three-dimensional pattern called a giant covalent structure.
