Giant covalent macromolecules

Remember: Covalent bonds form between non-metal atoms. Each covalent represents a shared pair of electrons. Covalent bonds are very strong. There are two types of covalently bound molecule: simple molecules (click here) and giant covalent macromolecules.   Carbon allotropes: graphite, diamond, amorphous carbon (soot, charcoal) and fullerenes are all examples of carbon allotropes. Allotropes are forms of an element that
