How does a molecule turn into a noticably tangible thing

AI Thread Summary
The discussion centers on the nature of molecules and how they can be made visible. It explores the concept of single molecules, particularly in the context of solids and liquids. Participants clarify that molecules can either aggregate or bond together through intermolecular forces, with liquids being collections of molecules that are close together, while solids have rigidly bonded molecules. The conversation highlights examples such as table salt (sodium chloride) and gold, noting that these substances can be composed of a single type of molecule or atom. The visibility of molecules is explained through their ability to scatter or absorb light, which becomes noticeable when present in large quantities. Additionally, the concept of crystals is discussed, suggesting that a crystal can be viewed as a large molecule due to the bonding of its constituent atoms. The dialogue emphasizes the importance of understanding molecular structures and interactions in the context of visibility and tangibility.

Firstly, i know this question is worded strangely, i wrote noticeably tangible because a molecule is a tangible thing but not visible to the eye without equipment. But my question is, how do we get a single molecule, and increase its size to be visible? For example a cup of water is like a collection of many water molecules. Are these molecules combing with each other or just near each other? What about a solid object? I can't think of any solid objects that are made of a single type of molecule off the top of my head...

I guess to kind of simplify my question. Do collections of the same molecule combine with each other or stack on top of each other? Or something else?

See "aggregation," or "bulk properties."

Water is a liquid and liquids are literally just individual molecules piled on top of each other. In solids, the molecules are rigidly bonded together.

Intermolecular forces are what makes molecules stick together. Also google for network covalent bonding.

Why not? Table salt is a sold at STP, and it is made up of a single type of molecule. Are you confusing molecules with atoms? Even then, gold is a solid, and it is made up of a single type of atom.
 
You may not notice a single gnat flying around, but you sure would notice 6.02x10^23 of them!

Similarly, single molecules will absorb or scatter very small amounts of light that are undetectable by the human eye. Large collections of these molecules, however, will scatter or absorb enough light to be noticeable by us.

Many, MANY molecules collected near enough to each other become tangible.

(Note: Table Salt is Sodium Chloride. STP is Sodium Triphosphate. Better name, Sodium Tripolyphosphate; )

STP means standard temperature and pressure.

I did not see earlier. "sold" was meant to be "solid"; "at" was not understood but misunderstood for "as".

My bad, I can't see or type well :smile:

What is a single molecule in a crystal? A crystal can be thought of as a really big molecule.
For something such as a NaCl ( table salt ) one can think all the atoms of sodium and all the atoms of chlorine as bonding together into one really big molecule. After all, each Na is bonded to all the chlorine atoms around it, and in turn each chlorine atom is bonded to all the sodium atoms surrounding it.
The unit Na-Cl is just the smallest representation of those atoms, and gives the molecular formula of table salt.

When an object is made out of a polymer, the single object may be a one single molecule, if you have the right type of polymer for which this is true.
