billions of atoms bonded together by strong covalent
bonds

Question 4

Describe the structure and bonding of small
molecules.

Answer 4

small numbers of atoms group together into molecules with strong covalent bonds between the atoms and weak intermolecular forces between molecules

Question 5

Describe the structure and bonding of polymers.

Answer 5

many identical molecules joined together by strong covalent bonds in a long chain with weak intermolecular forces between the chains.
