Solution
The main difference between molecules and lattices lies in their structure and composition.
Molecules are small groups of atoms bonded together. These atoms can be of the same element or different elements. The atoms in a molecule are held together by covalent bonds, which involve the sharing of electron pairs between atoms. Molecules can exist in all states of matter - solid, liquid, and gas.
On the other hand, lattices are continuous frameworks of atoms or ions. They are typically found in solid state substances, particularly in metals and ionic compounds. In a lattice structure, each atom or ion is surrounded by others in a specific, repeating pattern that extends in all three spatial dimensions. The bonds in a lattice can be ionic (formed through the transfer of electrons from one atom to another) or metallic (where electrons are shared among a 'sea' of atoms).
So, the correct answer is: Molecules are small groups, lattices are continuous frameworks.
