  1. All you need to do to start a molecule collection is to declare something to be your collection. Any object will do, even people.

    • Not true.
      Metals and salts are made of crystals, not molecules*. So if you name an object like a metal fork or an anvil or a metal container of table salt, your “collection” will not contain any molecules**.

      *Yes, there are salts that contain molecules, but the point is that there is no such thing as a salt molecule.
      ** Unless there are impurities.

      • mol·e·cule
        a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

        RIK fails at basic chemistry, not only are crystals made up of molecules but metals are not always in crystal form.

        • Please note that it doesn’t say anything about all substances being molecular. RIK’s point (which flew right over your head, it seems) is that there are many substances which aren’t composed of discrete units.
          Frankly, that you would go to the dictionary speaks volumes about your own scientific literacy. A better quick reference would be Wikipedia, which says “the majority of familiar solid substances on Earth…are not made of identifiable molecules”.

          • Sounds like a very poorly worded article. I can only assume they meant that most substances are made up of a mixture of different molecules. Just to give one example, there’s no such thing as a steel molecule, because steel is a mixture of iron and carbon (and possibly other elements) which combine but don’t chemically react. But just because there isn’t a discrete steel molecule, that doesn’t mean that steel isn’t made up of molecules.

      • Of course there’s such a thing as a salt molecule. When you combine one sodium atom with one chlorine atom, you get one molecule of sodium chloride, aka table salt. Saying that metals and salts are “made of crystals, not molecules” is ludicrous. It’s true that they have a crystalline structure, but what on earth do you think those crystals are made of? Spoiler: molecules!
