Latice structure on versus Polime structure

By Polime, do you mean polymer?

Yes I mean polymer.                                   .

They are two different things. From my understanding, you want to know the difference between a polymer and a lattice structure.

A polymer is a very large, chain-like molecule made up of monomers, which are small molecules. It can be naturally occurring or synthetic.



Notice the repeating molecules forming a large chain using hydrogen bonds.

You can think of a lattice like graph paper - it's a bunch of repeating units in a regular arrangement. Under the right conditions, you can add some more units to the lattice, like taping on another sheet of paper. Note that a lattice implies that you have a solid substance, because otherwise, the units can move around without forming a regular arrangement.

Part of the definition of a compound is that it has more than one element. So O2 is not a compound, but it is a molecule. Since it's a gas under normal conditions, it doesn't form a regular arrangement of repeating units - all the molecules are on their own.

H2O is a molecule, and a compound, since it has more than one element. In liquid or gas form, it doesn't have a regular arrangement, but when it freezes, it does freeze into a regular arrangement of molecules - that's why you get things like ice crystals.
