Polymers and Giant covalent structures

Polymers

• small units linked together to make a chain
• joined by strong covalent bonds
• strong intermolecular forces so more energy needed to break them
• solid at room teperature
• lower boiling points than ionic or giant molecular compounds

Giant covalent structure

• all atoms bonded together by strong covalent bonds
• very high melting and boiling points
• can't conduct electricity
• consists of structures such as diamond, graphite and silicon dioxide
